The question is why should he. Man City (Hart lol), PSG (rumored to want a replacement for Sirigu), Juve (need replacement for Buffon or did they get him?), etc would take him in an instant
He is better than you think mate. Villareal is on the list of the clubs I see regularly and Mussachio has always stood out plus he is young (23) and has the potential to improve and become WC. I rate him higher than Marcos who at 40m+ isn't worth it
For me a realistic and good defense would be
CB: Pique, Bartra, Mussachio, Fazio/Matheiu
LB: Alba, Adriano, Matheiu
RB: Alves?, Montoya, Aurier (please!)
Can't put to bed the possibility of an upset. Logically its Germany's to lose but Algeria with their high tempo style of play are more than capable of pulling an upset
