Born on the 11th October 2001, Finlander Viljami Sinisalo is currently employed as goalkeeper for Celtic, who he stands proudly for in his number 12 jersey. Standing at an intimidating 6ft 5in tall (1.96m) and weighing around 13st 9lb (87kg), Sinisalo has also wielded his size and skill in representation of Finland's national team.
According to Transfermarkt, his current market value is approximately £1m. The Finnish goal protector joined Celtic with a contract steadfast until the 30th of June 2029, with 3 years and 12 months left to run from this present moment.
Before his Celtic days, he started his career at Aston Villa as a trainee in July 2018. He was then loaned to Scotland's Ayr United in September 2020, only to return to Aston Villa in June the following year upon completion of his loan. His next destination would be a loan to Burton Albion in the English League One in July 2022, where he made his debut and showed his calibre with 4 first team appearances in that season.
Inevitably, he once again returned to Aston Villa on completion of his loan in December 2022. Another loan beckoned, this time to Exeter City in League One, in July 2023. However, his transfer to homeland neighbour Scotland's Celtic in July 2024 was not a loan but a permanent deal costing around £1m.
Dressed in the Celtic green, his first season 2024-2025 saw him make six appearances for the first team in league matches. Despite not having made any first-team appearances in the current 2025-2026 season, his presence in the Scottish Cup 2024-2025 matches, during which he made two starts, was well noted. Furthermore, his international contribution includes one start in the Euro Qualifiers 2022-2024 for his home country, Finland.
Though his current impact on the pitch may seem nominal, his potential contribution to Celtic's future successes remains constant.
