Aberdeen have signed Finnish winger Topi Keskinen from HJK Helsinki on a four-year contract.
The 21-year-old joins Pittodrie for an undisclosed fee and is manager Jimmy Thelin’s sixth summer signing.
Aberdeen says Keskinen had “numerous options in Central Europe and North America.”
He played twice against the Dons last season in the Europa Conference League group stage, with both matches drawn.
“Topi is a really exciting young talent who we believe will add some real quality to our team,” said Thelin.
“His arrival will reinforce our options in attack and he has all the attributes to be a great success at this club. His pace, creativity and also the fight and determination he shows will make him a great asset to the team.
“We believe this will be the perfect environment for Topi to continue its development and help it achieve international recognition.”
