I think he's playing too deep. Silva and De Bruyne are both higher up the pitch than him at the moment and it's pushing him into a more defensive role. Against West Brom and Barcelona he was absolutely brilliant because he played in the AM role. That's where he belongs and I think that should be higher priority than Silva right now because he's six years older.I think he's evidently got a lot of quality but he's not shown as much as I'd hope thus far. I remember him terrorising us when playing for Dortmund.
I think the system at the moment isn't getting the best out of him.
