Manchester United midfielder Paul Pogba has hit back at former club captain Roy Keane by declaring his critics "can say what they want."

Keane has been critical of the France international, branding him "a problem" ahead of the derby defeat to Manchester City on Wednesday.

But Pogba, who has scored 16 goals this season and was named in the PFA team of the year, said he pays no attention to what is said in television studios when asked specifically about Keane's comments.

"There's no problem," he told RMC following the 1-1 draw with Chelsea on Sunday. "They're paid to say things in front of the camera. I'm just focused on what happens on the pitch.

"They can say what they want, they're paid for that. I'm not paid to speak. I'm paid to be on the pitch and to fight for my team. That's all."

After the embarrassing 4-0 defeat at Everton, Pogba issued a public apology to supporters and said United had "disrespected" the fans who travelled to Goodison Park.

However, the interview prompted a furious response from Keane.

"I wouldn't believe a word he says," Keane told Sky Sports. "There's no meaning, no meaning behind it. I don't even think he believed what he was saying there. He is a big problem, no doubt about it.

"You've got to run back when you're defending. He said it got a bit heated after the game against Everton; I heard they were actually throwing their hair gel at each other."
