The deal includes a €37.5 million – including add-ons – obligation to buy at the end of the 2022-23 season, subject to certain conditions.

“Manuel is an absolute quality and security in midfield, bringing a level of class that few have. The giant steps he has made in the top flight, after a period at Atalanta and Milan’s youth teams, only confirms this,” Juventus said in a statement.

The Lecce-born midfielder, 23, scored twice in Italy’s 3-0 group stage win over Switzerland to help secure a last 16 berth for the eventual champions.

He has scored three times for Italy in 15 appearances.

Juventus endured a difficult campaign last season, with the defending champions finishing fourth under rookie coach Andrea Pirlo, leading to Massimiliano Allegri returning to take over as coach for a second spell.

They begin their 2021-22 Serie A season at Udinese on Sunday.
