Thierry Henry believes his former Arsenal teammate Emmanuel Adebayor was out of order with his celebrations in front of the Arsenal fans last week after scoring for his new club Manchester City.
The Togo striker ran the length of the Eastlands pitch to celebrate in front of the Gunners supporters after scoring in City's 4-2 Premier League win.
It sparked a furious reactions from the fans of his former club, and Arsenal legend Henry, now with Barcelona, took Adebayor to task over his actions.
The French striker told the Sunday Mirror: "The fans at Arsenal were great. They were and always will be my family.
"I never saw them behave badly so to react like they did at the weekend shows just how angry and upset they were.
"No matter what Adebayor's emotions were, he could have earned himself a lot of respect by not celebrating the goal.
"That would have shown real class and that to be honest is what most players choose to do when they score against their old clubs.
"I don't really understand why he didn't do that."
Henry added: "Arsene (Wenger) puts a lot of investment in you when he sees talent and I don't think it would hurt for Adebayor to show him, the club and the fans a little respect."
Adebayor has been charged with improper conduct for his controversial goal celebrations.
He has also been hit with a three-match ban after being found guilty of violent conduct following a stamp on Arsenal striker Robin van Persie's head in the game.
