Few things I picked out:
1) Napoli defended very well... seemed hard to break down.
2) Kompany needs new fucking boots! Great performance from him, but there two occasions where he slipped... one in first half where they hit cross bar and second half where he slipped and the ball fell straight to them. Happened a few times now, most memorable being the rooney overhead fluke.
3) Barry, struggling to keep up with the rest of the side... age starting to kick in I would say, takes a long time for him to shift the ball.
4) Richards over Zaba for me, if we take a more defensive approach to the game I would give Zaba the nod, but first half we needed Richards bombing it down that wing and overlapping Nasri/Silva.
5) Napoli were very good on the counter attacks, think Lescott did well overall.
Not sure what else to add to that... it was a decent performance, not to the standard we usually are and a win would of really helped.
