Former Chelsea midfielder Emmanuel Petit has slammed Chelsea fans for booing Mason Mount on his return to Stamford Bridge.

Mount, came on as a substitute against Chelsea at Stamford Bridge, much to the disgust of Chelsea fans.

Blues fans have labelled their former academy star as a traitor, following his move to Manchester United.

Petit has said it was an ‘embarrassing’ response to a player who first joined Chelsea at the age of six and spent the best part of two decades at the club.

“It was embarrassing that the Chelsea fans booed Mason Mount,” Petit told Genting Casino.

“However, you can’t just want to leave the club when things aren’t going well on the pitch, you have to be stronger than that mentally.

“Right now, he’s playing for Man United, one of the biggest clubs in the world, and you know what you signed up to when you signed for them.

“He’s coming back from a long-term injury, a professional footballer, and an athlete at the highest level must improve mentally.

“Before he was injured, he was playing like he walking on eggshells – very fragile mentally – and he’s kind of like Marcus Rashford at United.

“Mount arrived from Chelsea and he doesn’t look strong mentally. I used to be like that and it used to affect my performance on the pitch, but come on!

“You wake up in the morning, drive a Lamborghini, you need to look in the mirror! He was booed by Chelsea fans, but at the end of the day, he wanted to stay at the club.”
