Nasri missed plenty? He was just shit today, miles off the target. In that case Walcott's scuff in the last few minutes should have gone in, so should half the other stuff we punted at their goal.
My point is we ripped city up just as much as they ripped us up - but we didn't have the Aguero or Negredo to finish the work. The gypos pay a quarter of a million quid a week to three players in every position - of course they have quality all over the pitch. But they also conceded 3 at home and it could have been 6 or 7 with some decent finishing. That's surprising seeing as they spent the GDP of a small country trying to buy a defence.
