Inter have signed defender Alessandro Bastoni from Atalanta, but will loan him back to their fellow Serie A side for the next two seasons.
Italy youth international Bastoni, 18, has joined Inter on a permanent deal, although will not appear as a home player at San Siro until 2019 at the earliest.
He broke into Atalanta's first team last season, playing three Serie A games as his side were surprise fourth-place finishers, along with an additional Coppa Italia outing.
One of Bastoni's appearances for Atalanta came in a 7-1 away defeat against Inter, although his side had already conceded six before he came off the substitutes' bench.
