Not for City's titles hopes, surely, and not necessarily for the Liverpool game, but this will be a defeat which will live long in the memory for all the wrong reasons.
Yes, City will still win the league, although this defeat means they now need two more wins to get the job done at last. It really should have been today.
Had David De Gea not tipped over Aguero's last-minute header, and Sterling not somehow contrived to bundle against a post from a matter of yards, City would have at least had a draw, affording them the chance to win it at Wembley next weekend.
