Manchester City have completed the signing of French defender Aymeric Laporte from Athletic Bilbao on a deal until 2023.
The club have paid his £57million release clause, making him their record transfer.
The France U21 international issued a farewell message to all those involved with the Basque club in a post on their Twitter account on Monday, in which he thanked team-mates and fans for his six-year spell at the club.
The defender, who has made 19 appearances for Athletic this season, was left out of their squad to face Eibar on Friday.
Laporte previously turned down a move to the Etihad in October 2016 but the Premier League leaders have always remained interested.
