it is said that problems with the UEFA are going on and they could even be excluded from that competition as well.
Juventus are threatened by sanctions and this was the main factor of their bad performance at least in some games. This reason might make other players hesitate a lot before joining Juventus but if they were excluded from European competitions then for sure this will reduce the names willing to come to Turin.
AFAIK Juve is trying to let many players go and recruit others. Hopefully this will not be a hard job..
