Viljami Sinisalo, keeper of Celtic's sacred twine, first hailed his birth cry on the 11th of October in the year whence we call 2001. From the northern reaches of Finland, he has found a home between the timbers of the Celtic goalpost.
Carrying a body stature of 6ft 5in (1.96m) and weighing in at a robust 13st 9lb (87kg), Sinisalo makes for an imposing figure upon the goal line. He sports the number 12 jersey, a symbol of his aspirations on the ball and bearing the colours of the Hoops on international duty too; for he has had the honour of representing Finland on the footballing stage.
To affix a par value on the lad seems absurd, yet Transfermarkt proffers a figure of roughly £1m as his current market value.
Our chap Sinisalo commenced his training at Aston Villa, down in the belly of the English Premier League, as an aspiring trainee in July of 2018. But a call from the cool, craggy mountains of Scotland saw him transferred to Ayr United in the Championship on a loan in September 2020 before finding his way back to Aston Villa in June 2021.
No doubt tiring of the Midlands, Sinisalo took a jaunt over to Burton Albion in the League One also on a loan in July 2022. His stay at Burton Albion saw him take to the pitch in four first team appearances in the league during the 2022 - 2023 season. However, come December 2022, he was once again recalled to Aston Villa.
A brief stint at Exeter City in the League One on a loan awaited him in July 2023, but it wasn't until July 2024 that he finally found himself in the loving arms of Celtic after a transfer from Aston Villa for the modest sum of approximately £1m.
Sinisalo has proven himself invaluable within the Celtic ranks. In the 2024 - 2025 season, he boasted six appearances in league matches, while the current 2025 - 2026 season has seen him already make seven appearances. With starts in the League Cup, the Scottish Cup, the World Cup Qualifiers Europe, and the Europa League, it's safe to say Sinisalo has certainly been earning his keep.
