English Premier League side, Chelsea, have confirmed that Ola Aina has completed a permanent move to Serie A club, Torino, were he spent the last season on loan.
The Nigerian International impressed during the season-long loan spell at the club, featuring 30 times in the league and scoring once.
Aina would leave the club which he joined at the age of 11 and made six first-team appearances overall, including three in the 2016-2017 title-winning campaign.
As a youth player with Chelsea, the 22-year-old won the FA Youth Cup and UEFA Youth League winner.
Aina was called up to the Super Eagles squad and earned his full International cap after impressing while on loan at Hull City where he was a regular starter, making 44 appearances.
The deal for the versatile defender, who is in Egypt with the Nigerian national team preparing for the Africa Cup of Nations this summer, is reported to be around €10 million (£9m/$11m).
