WHAT? He just got there FFS, the season barely started! New country, new language, new teammates, new enviroment, new fucking side on which you drive the car?!! If that's what you're basing your opinion on, than I'm honestly sorry but I must say you're a fucking idiot.
Besides, he was included in last weeks team of the week and was pretty good against Arsenal. Give it few more weeks so the team gels and then come back here and say how wrong you were.
