Reports in Italy claim that Juventus forward Douglas Costa will be crucial in any negotiation to re-sign Manchester United star Paul Pogba.
The Brazilian has had a topsy-turvy spell in Turin since his arrival last year but he's increasingly becoming an important part of Massimiliano Allegri's plans, starting four of Juventus' last five games in Serie A since Christmas.
But Tuttosportclaim that Costacould prove to be the difference in negotiations with Manchester United's Pogba, who has frequently been linked with a return to the reigning Italian champions throughout this season.
