Viljami Sinisalo, a young Finnish goalkeeper, was born on 11 October 2001, which places the lad at 24 years of age. This towering figure, standing at 6ft 5in (1.96m) and weighing in at 13st 9lb (87kg), can certainly impose himself between the Celtic sticks, clad in the number 12 jersey. The lad's got international experience as well, having represented his homeland, Finland. Now part of the Bhoys, his estimated market value rings up to around £850k, according to Transfermarkt.
Before his arrival in Scotland, Sinisalo dipped his toes in the Premier League waters, becoming a trainee at Aston Villa in July 2018. A couple of years later, in September 2020, he moved from the plush Villa Park to somewhat modest Somerset Park, joining Championship side Ayr United on loan.
His Scottish sojourn was short-lived as he returned to Aston Villa in June 2021 upon completion of his loan. But he wasn’t at Villa for long. In July 2022, was off again, this time to League One side Burton Albion, also on loan. For the first season with the Brewers, 2022 - 2023, he made four appearances in the first-team.
However, he was recalled by Villa in December 2022, cutting short his journey with Burton Albion. Another loan move lay in wait for the young Finn. In July 2023, he switched to Exeter City, also in League One.
The beckoning call of Scottish football couldn’t be denied for long, and in July 2024, his nomadic journey led him right back, this time to Celtic, a move that saw Villa pocket a wee sum of around £1m. In his first season, 2024 - 2025, at Celtic Park, Sinisalo made six top-flight appearances, and so far in the 2025 - 2026 season, he has added one more to his tally.
Not just confined to the Premiership, Sinisalo got a taste of cup action, starting twice for Celtic in the League Cup 2025 - 2026, and twice in the Scottish Cup 2025 - 2026. Internationally as well, he remained involved, starting twice for Finland in the World Cup Qualifiers Europe 2024 - 2026.
