I think we need a sense of perspective here. Yes, Kompany missing is a BIG loss for Man City, he's a beast of a player and has performed superbly this season... BUT they have a good squad with a lot of depth and can bring players in that would get in to over half the teams in the Premiership.
We have struggled this season against worse teams than the side City are likely to field tomorrow!
Anyone who saw how they performed with only 10 men on the pitch in the 2nd half against United will see that they have a lot of quality, and they can cause a lot of promblems, so let's not get carried away...
I said before the Kompany incident, before it was rumoured Silva/Balotelli/Dzeko would be missing that I would take a (score) draw tomorrow and that hasn't changed at all.
No harm in being confident, but we should still respect them.
