Viljami Sinisalo, born on 11 October 2001 (age 24), is a Finnish goalkeeper with Celtic. A towering presence at 6ft 5in (1.96m), he wears the number 12 shirt and joined the club from Aston Villa in July 2024 for around £1m.
His earlier career included senior football away from Villa, with Burton Albion giving him league minutes in 2022-2023, but Celtic has quickly become the serious part of his story. Across two seasons he has made 18 league appearances for the club, with his role growing in 2025-2026.
This season, Sinisalo has been a regular first-team presence, making 12 league appearances along with two in the League Cup, four in the Scottish Cup and one in the Europa League. He has also remained involved with Finland, featuring twice in European World Cup qualifying.
His current market value is around £850,000, according to Transfermarkt. At Celtic, he is no longer just a squad goalkeeper from Aston Villa; he is part of the working shape of the current side, still with plenty of career ahead of him.
