Ola Ain has joined Torino on a permanent basis from Chelsea in a deal worth £8.9m (€10m).
Chelsea have confirmed the London-born Nigerian's departure after he impressed during his one-year loan stint at the Serie A club, making 32 appearances and scoring once.
Speaking to Sky in Italy on Monday, Torino president Urbano Cairo said the club had exercised their option to buy Aina with the current deal set to expire at the end of June.
"We exercised our option to buy Ola Aina, as well as [Christian] Ansaldi and [Koffi] Djidji," he said. "Now Torino own all their players."
The 22-year-old international had renewed his Chelsea contract at the end of last season, signing a deal to keep him at Stamford Bridge through to 2021.
He made his first-team debut for the Blues in a League Cup win over Bristol Rovers in 2016 having progressed through their academy, where he won two UEFA Youth Leagues and two FA Youth Cups.
Torino finished in seventh place in Serie A this season, missing out on a spot in the Europa League qualifying rounds.
