Manchester United hero Paul Parker has concerns over new manager Jose Mourinho.

The former Chelsea boss' two spells at Stamford Bridge were littered with bust-ups with rival managers.

"His style worries me," Parker told talkSPORT. "When he had his press conference and he brings up Arsene Wenger – that worries me.

"He shouldn't be talking about it, it's irrelevant.

"If he wants that personal battle he should do it on his own time but don't use Manchester United to do what you were doing at Chelsea.

"He's not managing Chelsea anymore."
