Manchester City boss Mark Hughes was less than impressed by Arsenal counterpart Arsene Wenger's behaviour following the Citizens' 3-0 Carling Cup quarter-final victory over the Gunners.
Wenger refused to shake hands with the Welshman following the final whistle at Eastlands, having seen City set up a semi-final with Manchester United thanks to goals from Carlos Tevez, Shaun Wright-Phillips and Vladimir Weiss.
Hughes commented:"At one point I was over on his side of the technical area and he seemed to be a bit aggrieved by that, but I think he is probably more aggrieved because he got beaten.
"I have been to the Emirates Stadium and been beaten 6-2, but I still offered my hand at the end. It is the least you can do.
"I am a little bit disappointed in that respect. You should be a bit more gracious than that because it is unnecessary.
"We all hurt when we get beaten. No-one is more upset than me, but you should always offer your hand.
"There has been a little bit of negativity around in recent weeks. That has been taken away this evening.
"We are 16 or 17 games into the season and we have still only been beaten once. Not many City teams in the past have been capable of that – that is why we have invested so much money."
