If you have seen Dzeko play as often as i have you would know this was a one off, i think he was more annoyed with himself than RM as he isn't playing as well as he was when the season started and knows he will lose his place in the starting 11 if he doesn't improve, he is not the first player to show emotion and wont be the last, he has apologised and that's good enough for me.
Tevez has shot himself in the foot and has gone from hero to zero in my eyes, if he never pulls a City shirt on again i will be more than happy.
As for RM not having man management skills what was he to do, Tevez refused to play what would any manager have done in his place?
RM said after the game Tevez will never play for City again, i hope the owners back him.
