Born on the 11th of October 2001, the Finnish goalkeeper Viljami Sinisalo is currently associated with Celtic, wearing the number 12 jersey. Standing at a towering height of 6ft 5in (1.96m) and weighing in at 13st 9lb (87kg), Sinisalo is an imposing presence between the sticks. Apart from his club commitments, he has also made his mark at the international level, representing Finland. As per Transfermarkt, his current market value is estimated to be around £1m.
His journey in professional football commenced as a trainee at the Premier League side, Aston Villa, in July 2018. Two years later, in September 2020, Sinisalo was loaned out to Ayr United in the Championship in Scotland. After a season-long stint at Ayr United, he returned to Villa in June 2021.
However, the same summer saw another change in his career trajectory as he was sent on another loan deal to Burton Albion, which competes in League One, England's third-tier professional football league. Sinisalo was able to make four appearances for the first team in league matches for the 2022-2023 season. His time at Burton Albion came to an end in December 2022, when he was recalled to Aston Villa.
His third loan move was in July 2023, this time to Exeter City, another club in League One. His consistent performances grabbed attention and led to a permanent move to Celtic in the Scottish Premiership in July 2024 for a rumoured fee of around £1m.
Sinisalo's time at Celtic has so far been characterised by steady progress. During the 2024-2025 season, he made six first-team appearances in league matches. And, in the current 2025-2026 season, he's already made two first team appearances for the hoops. His appearances have not just been restricted to the league matches; he's also been involved in cup competitions. Sinisalo started Celtic's League Cup and Scottish Cup fixtures during the 2025-2026 period. Internationally, he held the gloves for Finland in the 2024-2026 World Cup Qualifiers Europe and donned the green and white for Celtic in the 2025-2026 Europa League.
