I don't think it's due to lack because even Allegri recently admitted that us having learnt to be patient is a part of our recent successful run of games.
Apparently not necessarily. The club believes in Fagioli and Miretti that are already in the squad and also consider Rovella and Ranocchia players that may come back next season. Therefore, even if we sell McK we might not see a direct replacement.
No way he's gonna accept the Bournemouth of this world. I think he thinks very highly of himself and will be waiting for an offer from a club fighting for the top 4. Maybe Newcastle would be dumb enough?
