Does that include the three times he took on his man and beat him, twice in the box, once resulting in narrowly missing with a curling effort, the other a great rolling pass that for some reason the receiving player decided not to hit first time? For the first 25 minutes he was wreaking havoc and then Sunderland began dropping and double covering to stop it.
He did not set the world a light but he was actually fairly good while he was on. And, although you said you are not passing judgement, I think saying "so far I don't see what he brings to the side" from his first competitive performance is doing just that. How many said the same thing about Silva, Yaya, or Kompany? I actually remember getting in to a bit of heated debate with a fellow blue that thought Kompany was an utter waste of money and could not understand why we bought such a "precious" defensive midfielder.
Anyway, that's my daily rant done.
