Football Club Midtjylland
On 1 February 2016, it was confirmed by Football Club Midtjylland, that they had signed with Kairinen.
Left-footed and very confident on the ball, Kairinen reads the game exceptionally well. He also has a great range of passing and can shoot from distance.
Local journalists consider him the best young talent in Finnish football and expect him to develop into a deep-lying midfielder in the Andrea Pirlo mould. Still only 17, Kairinen"s ability to control midfield is remarkable in one so young.
His understanding and vision are already impressive, and he seldom seems to be in a hurry, picking his passes with elegance and precision.
Deployed largely in an attacking role, he has shown an aptitude for defensive work too.
