Well that's the defensive corner I'm talking about. Saha off for Distin and pushing Heitinga to midfield and Fellaini to attack isn't really a that bad option. But after you've made that change, there's no way you can sub yourself back in to chasing the game.
Indeed, striker off for a defender for 10-15 minutes of the game and you're pretty much out.
How he tried to save the game with McAleny in the last 5 minutes irritated me more than anything.
