Eetu Vertainen

Vertainen began his youth career with KyIF, before joining the academy of HJK at the age of 11. He started his senior career with Klubi 04, before playing for HJK and Ilves in the Veikkausliiga. Vertainen signed a two-year contract with Scottish club St Johnstone on 1 September 2021. He moved on loan to NIFL Premiership club Linfield on 7 February 2022. On 19 March, he scored four goals in a 5–0 league win over Dungannon Swifts. On 30 June, his loan deal with the Northern Irish team was extended. Following his performances, he was named the league's Player of the Month and won the Goal of the Month award for December 2022. In January 2023, he scored hat-tricks in successive league matches. Later in the same season, he was the subject of speculation about a permanent transfer to Linfield, as well as links to Welsh club The New Saints. On 1 September 2023, Vertainen joined Serie C club Triestina on a permanent deal. Since Triestina were unable to register him on time, on 11 September he was loaned to Super League Greece 2 club Athens Kallithea until the end of the year, with an option to extend the deal for the rest of the 2023–24 season. In January 2024, Vertainen returned to Triestina, and made his Serie C debut on 7 January 2024, as a starter in a match against Trento.
