The Uruguay international joins new Juve man Federico Bernardeschi in leaving Florence, as he prepares to sign with the Nerazzurri
Matias Vecino is set to join former team-mate Borja Valero at Inter Milan after Fiorentina confirmed the San Siro club had met the midfielder's release clause.
Inter 11/1 to win Serie A
Valero has already made the move from La Viola to Inter this month, signing a three-year deal, and Vecino will follow him subject to passing a medical.
Inter have agreed to pay €24million to sign the Uruguay international, who appeared in 31 Serie A games for Fiorentina last season.
As well as selling Valero and Vecino to Inter, Fiorentina have lost Federico Bernardeschi during the transfer window, the Italy winger joining Serie A champions Juventus for €40m.
Inter, meanwhile, are reportedly close to completing the signing of Nice left-back Dalbert as the club's new head coach Luciano Spalletti adds to his squad for the coming season.
