Roy Keane slammed Paul Pogba ahead of the Manchester derby, referring to the Red Devils midfielder as "a big problem".
Pogba spoke to Sky Sports' Laura Woods before Wednesday night's match where he apologised for United's 4-0 defeat by Everton.
The World Cup winner spoke about the attitude problems at the club, and admitted players aren't working hard enough for the shirt.
He also suggested there would be a reaction from the players to the shocking defeat against the Toffees.
But Keane isn't convinced Pogba is speaking from the heart.

"I wouldn't believe a word he says," said Keane on Sky Sports.
"There's no meaning behind it. I don't even think he believed what he was saying there. He's a big problem."
Gary Neville was sitting next to Keane when he made the remark, and Man United fans noticed he couldn't help but laugh.

While another added: "Neville's reaction was brilliant," while a third said: "Haha was funny did you see Neville at side of him."
