Maybe if we kept Vidal we would have signed Siqueira instead of Alex Sandro, so to me it was a good move. We went for a 3 man midfield again, and it was still top (Sami, Pogba, Marchisio), with good enough backups. We didnt have another playmaker other than Marchisio, hence Nanes. I dont recall a better player that was available back then, for the role we bought him in for
