I picked Silva.
He already has chemistry with the core of our team.
He plays on the left wing, although not right footed.
He is proven that he can play in the midfield role.
I think he can play a role similar to what Iniesta can do, that is play on the left and in the center.
Having these two players being able to switch on the fly would be great for the team.
Selling point is that Silva is a quality versatile player who would succeed at Barcelona because of his already existing chemistry through Spain
