Potential buyer(s): Tottenham look likely after losing patience with Erik Lamela. Southampton and Everton would also welcome someone of his calibre.
The former Porto star's attacking quality attracted widespread attention from several big clubs this summer.
Juventus eventually won the race to sign the left-back on a five-year deal, but if his form continues, alongside the Old Lady's drop in form, interest will continue to surround the defender.
He’s quick, defensively sound and a threat going forward, so it would undoubtedly take a large sum to prize him away from his new club.
Potential buyer(s): Manchester City are lacking in a world-class left-back - don’t be surprised if they try an audacious bid.
