No idea. Don't even know if Man Utd will have any interest in selling.
But sooner or later Man Utd are going to reshape their squad and there are going to be interesting players made available to finance it.
Now would be the time to sell Lichtsteiner if you are keen on recouping most (if not all) of the cash Juve paid for him.
But I see no reason to believe Lichtsteiner doesn't have at least a couple more good seasons in him, so I wouldn't particularly object to Juve giving him a new contract.
I like Lulic. Not going to suggest he is a better player than Asamoah, but he probably is more balanced as a wing back.
I'd also like to see one of Juve's wing backs be comfortable enough as a wide midfielder so that Juve could easily change to a back four.
Your system can easily become:
Buffon
Lichtsteiner-Barzagli-Bonucci-Chiellini
----Vidal-Pirlo-Pogba----Lulic
Tevez
