Lucho, said in his post match yesterday, how Paco is the same player as he was when he got here but he's more confident.
Here's a video of him last season with Valencia. It's actually interesting, despite not playing as much and when you compare his minutes to guys like Gomes, he's improved and he put in a lot more effort into trying to play as how a Barca striker should.
I mean two different positions obviously (Midfield vs Striker) but out of the two Valencia players, Paco is putting more of an effort and fight to impress and improve. It sucks that his price tag will haunt him though (30 Million).
