Juventus face competition from Ajax for Gremio fullback Felipe Mattioni Rhode.
The 20 year-old is a £6 million target for Juve after chief scout Renzo Castagnini recommended his signing after a scouting trip to Brazil earlier this month.
Juve want Mattioni in January as cover for Zdenek Grygera, but must see off Ajax, which are banking on their close relationship with the player's Italian agent, Mino Raiola, to trump the Bianconeri.
