Arsenal defender Shkodran Mustafi is not happy with club legend Emmanuel Petit.

The German defender spoke at length about how he felt that he was blamed for defeats, even when they were not his fault.

And among those who spoke negatively about him in public, he singled out French World Cup winner Petit for particular criticism.

"That annoyed me a lot [Petit calling him the king of blunders]," he told Der Spiegel.

"It's the one thing when fans or media criticise you. But it's a different story when an ex-player who knows how hard it is on the field sometimes says so.

"I expect such players to be more sensitive and realise what this sharply worded critique can trigger. In the past, that might have been in the paper one day, and then people would have forgotten it. Today it's on the Internet and will haunt me for the rest of my career.

"Former players like Petit should not have to make a name for themselves by making condescending comments about current players."
