It's interesting that Manchester City's opener came immediately after a horribly shanked clearance from Edwin van der Sar, because a few minutes before that it was Joe Hart who did much the same thing with a scuffed punt that nearly went straight to Dimitar Berbatov at the edge of the area. Fortunately for City, the Manchester United striker couldn't quite get on the end of that one, and they'd take the lead in a mirror scenario at the other end of the pitch.
Yaya Toure's opener hasn't seen City drop into a defensive shell like many might have expected - they're still going for it and severely testing a shell-shocked United defence. Although the goal hasn't quieted the red half of Wembley, who are still singing along quite happily, it's given City some extra impetus and they look more likely to grab their second than their opponents do to equalise. United have done nothing yet this half.
