Viljami Sinisalo, born 11 October 2001 in Finland, is the record-breaking goalkeeper for Celtic. Standing at an imposing 6ft 5in (1.96m) and weighing in at 13st 9lb (87kg), he positions himself between the posts wearing the number 12 jersey. Along with his club duties, Sinisalo secures the net for the Finland national team. Transfermarkt values the Finnish shot-stopper at around £1m.
The promising talent first caught the eye of international football when he joined the Premier League club Aston Villa as a trainee in July 2018. The first attempt of Villa to mould Sinisalo into an English football product was his transfer to Ayr United, a Championship outfit in Scotland, on loan in September 2020.
However, June 2021 saw Sinisalo return to Aston Villa, concluding his loan stint with Ayr United, only to be loaned out again in July 2022. His new venture took him to Burton Albion, a club competing in England's League One. His debut season (2022-23) with Burton Albion comprised four first-team appearances in league matches.
Despite his nascent career, the young goalkeeper has spent a significant amount of time at loan, further evidenced by his subsequent loan move to Exeter City, another League One team, in July 2023. This pattern of Sinisalo's career path continued until July 2024 when he made a definitive transfer from Aston Villa to the Scottish giants, Celtic, for a sum of approximately £1m.
Upon Sinisalo's arrival at Celtic, the 2024-25 season saw him guarding the goalpost in six first-team league matches. Whereas, in the current 2025-26 season, Sinisalo has already made four first-team appearances in league matches with plenty of football still ahead. In the same season, his performance has enabled him to start in two League Cup matches, three Scottish Cup games, two World Cup Qualifiers for Finland, and one Europa League fixture for Celtic.
