Not pessimistic, just realistic. I don't jizz in my pants for just anything. If he was really as amazing as people seem to make him be, Madrid would've never sold him. And he certainly would've got more playing time there. I'm not against him, i'm just not convinced.
I also don't trust this "new" Spanish generation will be something to write home about. So yes, you're goddamn right I'm suspicious about him.
