Apparently Vidal could get to Chelsea, can that be a reason for Sanchez to arrive at Conte's team?
It's reported quite often in Chile around international tournaments that Vidal and Sanchez aren't friends. After they failed to qualify a lot of controversy was kicked up around there being parts of the dressing room lead by Vidal who spent as much time drinking and partying on an international trip than training or playing football.
Bravo and Sanchez apparently get on very well though.
