We don't need to sell tevez to finance anyone when we have an abundant of perfectly good players who can get us the cash we need. in this case Vucinic plus cash is of interest to Spurs. In saying that, Lamela was bought for decent money but hasn't set the world on fire and hasn't been able to make any impact, so I highly doubt Spurs would want to try and even recap what they paid for him. That just wont happen regardless of juve, inter or any other team showing interest.
Agree on marchisio, makes too much sense for me...a bench player who can get us that kind of money which we need would be ideal.
Lamela can fit into a 4-3-3 easily...conte has not used this due to the lack of players to utilise it. he obviously hasn't got any faith in Gio playing on a wing in that formation, his love child pepe has been injured and isla just isn't good enough. Keepin mind vuci was injured for a while as well.
