Paul Pogba said “the time is right to go back to Old Trafford” after completing his world-record £89m transfer to Manchester United.
The 23-year-old midfielder returns after four years away, having left United for Juventus for £1.5m in 2012.
Pogba, who signed a five-year deal, added: “This is the right club for me to achieve everything I hope to.”
Manager Jose Mourinho said the France international could be “the heart of the club” for the next decade.
United will pay the Italian champions 105m euros for Pogba, plus 5m euros (£4.5m) in performance-related bonuses and other costs, including 5m euros if Pogba signs a new contract.
It surpasses the £85m that Real Madrid paid Tottenham for Wales forward Gareth Bale in 2013.
The announcement was made by United just after 00:30 BST on Tuesday, with a glossy video showing the player – with a red devil marked into his hair – emerging from the shadows.
It was followed by a series of sponsor videos, including one with English rapper and grime artist Stormzy, whose most successful song to date is ‘Shut Up’
