I can remember a few seasons ago when we used to play a lot of games where we had loads of shots and the opposition hardly any, yet we would still contrive not to win.
There was a game against Sheffield United just after the Invincibles season, where we drew 2-2 and we had 32 shots and they had one, which they scored and we had an own goal, and on Match Of The Day they said Sheffield United deserved the draw which to me was ridiculous.
Their argument was that they had defended well, and I have heard that several other times in very one sided games.
I watched that Man U game against Burnley and as much as I enjoyed not seeing them win, they should have won easily.
It's games like this that can decide a PL title which is usually won by a few points, and there have been a lot of occasions where we have dropped points even though we were the far better team, having far more shots.
There is also the factor of dodgy refereeing decisions which can go for or against a team.
I don't have a lot of sympathy with Man U or Mourinho because they have both benefited from decisions that have gone for them in previous seasons, but I also think this season they should have more points from games where they have dominated.
