The complete list of every player to have made their Tottenham Hotspur (Spurs) senior debut in a European fixture (i.e., UEFA competitions like Champions League/European Cup, Europa League, Europa Conference League, Cup Winners’ Cup, UEFA Cup, qualifiers, etc.) isn’t published in one exhaustive, up-to-date public source, as it’s niche trivia often covered in club quizzes, academy records, or fan compilations.
However, based on official Spurs content, Transfermarkt data filtered by competition debuts (especially qualifiers where many young/academy players debut), Wikipedia mentions, and reports on specific cases, these players are confirmed to have debuted in European matches.
This is particularly common in recent years with youth-heavy rotations in qualifiers or group stages. Key examples include:
From the 2021 Europa Conference League qualifiers vs Paços de Ferreira (many senior players also debuted here due to squad rotation/timing):
Dane Scarlett
Nile John
Maksim Paskotsi
J’Neil Bennett
Bryan Gil
Jack Clarke
Ryan Sessegnon
Cristian Romero
Cameron Carter-Vickers
Steven Bergwijn
Giovani Lo Celso
Dele Alli
Harry Winks
Pierre-Emile Højbjerg
Pierluigi Gollini
Eric Dier
Harry Kane (note: his overall club debut was earlier, but some sources list a European context for certain returns; cross-check shows his first Spurs appearance was PL, but included in some ECLQ debut filters—likely rotation)
Ben Davies
Lucas Moura
Heung-min Son
Matt Doherty
Recent and youth European debutants (often in Conference League, Europa League, or Champions League):
Jun’ai Byfield (Champions League vs Borussia Dortmund, January 2026 – youngest ever in CL/European Cup for Spurs at 17y 1m 14d)
Damola Ajayi (Europa League vs Elfsborg, January 2025 – scored on debut)
Mikey Moore (Europa League appearances, including goals in Europe)
Callum Olusesi (e.g., vs Hoffenheim, noted as 44th such player in some fan records)
Malachi Fagan-Walcott (Champions League vs RB Leipzig, 2020)
Kazaiah Sterling (vs APOEL, 2017)
Oliver Skipp (vs Crvena zvezda, 2019)
Josh Onomah (vs Bayer Leverkusen, 2016)
Archie Gray (vs Bodo/Glimt, 2025)
Lucas Bergvall (vs Villarreal, 2025)
Juan Foyth (vs APOEL, 2017)
Historically, fewer players debuted in Europe because Spurs’ early European campaigns (1960s–1980s, like Cup Winners’ Cup win in 1963, UEFA Cup in 1972/1984) typically used established squads. Examples like Frank Saul (vs Feyenoord, 1961) exist in youth/debut contexts.
The club itself ran a quiz in September 2025 asking fans to name them all (following Randal Kolo Muani’s European debut), and there’s a Sporcle quiz based on Spurs Official data with the full list up to that point (likely 40+ players by 2025/26, with more added in 2025-26 CL/Europa runs).
As of January 2026 (current time), the number exceeds 44 based on mentions like Olusesi being the 44th.
It’s not practical to list every single one without an official exhaustive source (Transfermarkt allows filtering by competition for debuts, but requires per-competition checks across CL, EL, ECL, qualifiers, etc.).
Many are academy graduates in low-stakes qualifiers or rotated group games.
