Hughes: Wenger should be gracious in defeat
Wenger refused to shake hands with Hughes after City's 3-0 victory over his young side at Eastlands, unrepentantly telling reporters later that "perhaps I have no professional courtesy."
"Maybe he's used to winning games and when he does lose sometimes he doesn't know how to behave," Hughes, who said he had a lot of respect for Wenger and his achievements, told the BBC.
"At one point I was over on his side of the technical area and he seemed to be a bit aggrieved by that," he added.
"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, but you should always offer your hand."
