Grégoire Świderski Scouting Report: Alavés’s 21-Year-Old Reserve Goalkeeper

Quick answer. Grégoire Świderski (21) is Deportivo Alavés’s No.31 goalkeeper, third in the club’s first-team pecking order, and has yet to make a single La Liga appearance as of this report. Born in 2005 in the Bordeaux/Bruges area of France to a Canadian father and a French mother, he is reported by some sources to have Polish heritage through his paternal grandfather and by others through his maternal grandfather. He joined Alavés B as a free agent from the Bordeaux academy in either August 2024 or January 2025, depending on the source, on a deal running to 2027. He played six matches for Canada’s U20s at the 2024 CONCACAF U-20 Championship, and press reports placed him in a Canada senior squad environment in June 2024, though no verified senior cap appears in the sources used for this report — some describe that call-up as a “training player” role rather than a full squad inclusion. His height is listed anywhere from 1.87m to 1.90m depending on the source. He has reportedly played a handful of matches for Alavés B in the Segunda Federación (Spain’s fourth tier) this season, with the exact total disputed between sources (4 or 5). GegenSports rating: 52/100 — not a finished product, but a goalkeeper with real physical upside who must be judged cautiously given the lack of hard performance data.

Note: because no official La Liga statistics exist for Świderski (0 appearances), this report relies mainly on Alavés B / Segunda Federación data, career history and international records. Transfermarkt and FBref’s full player pages could not be accessed. Conflicts between sources — on birthplace, height, transfer date and national-team status — are flagged throughout.

Profile and biography

Career and transfer history

Świderski’s path is that of a young goalkeeper who left a major French club’s academy — Bordeaux, during a period of financial turmoil and relegation at the club — for a reserve-team role at a La Liga side. Wikipedia and TheAnalyst credit him with somewhere between 58 and 62 appearances for Alavés B across the 2024-25, 2025-26 and 2026-27 seasons, though the season-by-season breakdown is inconsistent between sources. Having never played a first-team minute places him firmly in the “promising but unproven” category.

Alavés B / Segunda Federación data

No detailed goalkeeping metrics — saves, goals conceded, clean sheets — could be sourced for Świderski for this report; available sources only give match and minute counts, and even those conflict.

Terms: the Segunda Federación is the fourth tier of the Spanish football pyramid, where most La Liga and Segunda División clubs field their B teams. A keeper being on the first-team roster while playing for the B side is a development model similar to how some big Turkish clubs use their U19/U21 leagues for backup goalkeepers. Because this report’s data set contains no verified save percentage or comparable performance metric for Świderski, the style analysis below leans heavily on physical profile and career context rather than in-match data.

Świderski in Alavés’s context

Alavés has a clear goalkeeping hierarchy: No.1 Antonio Sivera (captain, unquestioned starter), No.2 Adrián Rodríguez (1.95m, experienced backup) and No.31 Świderski third in line. That means his chances of regular La Liga minutes in the near term are slim, and his development will likely hinge on performances at Alavés B and a possible loan move. The club keeping him under contract to 2027 can be read as a sign they view him as a long-term project — though that is no guarantee of a short-term first-team opportunity.

Playing style analysis

Physical profile. At roughly 1.87-1.90m, his height offers a solid physical base by modern goalkeeping standards, which could be an asset both in shot-stopping and on crosses. However, no independent data on his positioning (getting his body in the right spot before a shot is struck) or reflex quality could be sourced for this report.

Experience level. With zero La Liga minutes and a limited Segunda Federación sample, making a concrete, data-based judgement on his distribution, box command (how confidently a keeper commands his own penalty area) or sweeper-keeper qualities (interventions outside the box) would not be grounded in evidence at this stage. This is the clearest and most honestly stated limitation of this report.

National-team context. His six caps for Canada U20 show he is at least on a federation’s radar internationally. His inclusion in a senior squad environment (however disputed the exact status) can be read as an indirect signal of talent, but it is a potential marker, not a performance data point.

Strengths

1. Physical height advantage: a 1.87-1.90m frame is a solid physical foundation for goalkeeping.
2. Early international interest: a regular in Canada’s U20 squad and reportedly included in senior-team circles.
3. Big-club academy background: came through the academy of Bordeaux, a historically significant French club.
4. Long-term contract security: a deal with Alavés to 2027 suggests the club is giving him time to develop.
5. Multi-national flexibility: his Canadian, French and possible Polish connections give him options across different national-team pathways.

Weaknesses

1. Zero top-flight match experience: has never played a La Liga minute; no proven performance at the professional level.
2. Very limited data transparency: basic goalkeeping metrics such as saves, goals conceded and clean sheets could not be sourced for this report.
3. Third in the club pecking order: while behind Sivera and Adrián Rodríguez, regular first-team football is unlikely.
4. Unclear national-team status: reports of senior involvement are limited to vague language like “training player,” with no confirmed cap on record.
5. Source conflicts: even basic facts like birthplace, height and transfer date are inconsistent across sources, suggesting his profile is not yet well documented.

GegenSports rating: 52/100

This rating is not imported from another platform; it is built solely from the limited data gathered in this report: physical profile 11/15, development potential 14/20, international interest 9/15, proven performance (La Liga/Segunda Federación) 6/25, club standing and opportunity 5/15, data transparency/visibility 7/10. Total: 52. This may look low, but it reflects a lack of top-level data rather than weak ability; it could shift significantly after a loan season or a handful of first-team appearances.

Comparable players

Profiles close to Świderski’s “academy product from a major club, physically equipped but still chasing top-level minutes” type include Diego Kochen (a Barcelona academy product seeking minutes on loan at Lyngby — a directly parallel theme), Sherkhan Kalmurza (a 19-year-old attracting international interest with limited top-level experience of his own) and, inside the same squad, Adrián Rodríguez (a step further along a similar “second-tier goalkeeper” journey at the same club). This trio was chosen to illustrate both the paths available to Świderski and where he currently stands.

Süper Lig fit and suitable Turkish clubs

Świderski’s profile is too early for a Süper Lig club seeking an immediate starting goalkeeper; it suits clubs that want to add a physically developed young keeper to a watchlist and assess him through a youth/U21 pathway or a loan arrangement. The following is profile analysis only, with no knowledge of any actual club contact.

• Göztepe: a club with a clear recent track record of developing young players from academy to first team, structured to assess a goalkeeper over a two-to-three season project.
• Kasımpaşa: a mid-table club with a tradition of goalkeeper rotation and giving young players chances; suited to a low-cost, long-term bet.
• Gaziantep FK: a club profile with a higher risk tolerance for giving young foreign players development space.

Adaptation score: 5/10. Rationale: having already lived in both France and Spain gives him a multicultural background, which is a plus; but there is no prior data on adapting to Turkey, and at 21, with limited experience of high-pressure senior football, this projection remains largely speculative. Ideal teammates: an experienced centre-back pairing comfortable receiving the ball from the keeper and giving a young goalkeeper confidence; a patient goalkeeping-coach structure that can accelerate his development.

Cost and value-for-money scenarios

No market value or transfer-fee information exists in this report’s sources. Having joined Alavés as a free agent (Wikipedia) suggests any future move could also come at a low or nominal fee, though his contract running to 2027 means Alavés is under no pressure to release him for free. The most realistic value scenario is a club taking him on loan to secure regular game time and monitor his progress closely; a straight permanent transfer with a fee attached would be a riskier proposition given the current lack of data.

Development potential, injuries and durability

Development potential is the single most defining factor in assessing a 21-year-old who has yet to debut in La Liga. His physical profile (1.87-1.90m) and a track record of regular minutes across multiple academies (Bordeaux, Alavés B) at a young age are positive signals. No injury record appears in the sources used, though this may simply reflect his limited game time — an infrequently-used player naturally shows a thinner injury history. The next two-to-three seasons represent a critical window that will shape the direction of his career.

Foreign player quota and UK work permit (GBE)

As a Canadian citizen, Świderski does not have EU/EEA free movement rights and would be treated as a foreign player in Spain and other EU countries (whether a French or Polish family connection gives him a route to an EU passport could not be confirmed in this report). Türkiye’s foreign-player quotas are reset by the TFF each season, so current regulations should be checked separately. Under the UK’s Governing Body Endorsement (GBE) system, the number of official senior caps is a decisive criterion; Świderski’s status here (camp inclusion reported, but no confirmed cap) is a serious source of uncertainty for any GBE scoring. This is not legal advice.

Suitable leagues

• Segunda Federación / Segunda División (his current development environment)
• Süper Lig clubs with strong U21/academy pathways (a low-cost, long-term bet)
• Ligue 2 (a plausible loan option given his French connection)
• MLS / Canadian Premier League (a plausible option given his national-team ties)
• Belgian Challenger Pro League-type development leagues (as a loan scenario)

Sporting director summary

Sign: for clubs seeking a low-cost, long-term goalkeeper project with the patience to let a young player develop (a loan arrangement is recommended). Wait: for clubs needing an immediate starting goalkeeper or demanding proven top-level performance; the data is not there yet. Risks: zero top-level match experience, limited data transparency, unclear national-team status. Recommendation: add to the watchlist; reassess after a loan season.
