I have been thinking about this, and just the fact the it is so difficult to decide shows you that the lad scores some belters!
For me though, it has to be the one against Newcastle, because that is the one that requires the most technique, anticipation, creativity... you name it. Amazing goal. And the fact that I was standing in the Kop when he scored it probably makes me a bit biased to pick that one.
Special mention to the 2nd free kick against Zenit though. The perfect combination of power and curve.
