I find Mata more complete then Silva. He can pull of an amazing cross, his positioning is top notch and his FKs are special. I think Silva is on a higher level now though as he has gotten used to PL and is bit older then Juan. Actually, I expected a lot more of Mata next season when we bring more dangerous players that will take the pressure away from him. Not only that, but Juan needs some rest and he is improving his game a lot by each passing match.
