Keane launched a blistering attack on Paul Pogba last month after Manchester United’s 4-0 drubbing at Everton and suggested the Frenchman is a liar.
“I wouldn’t believe a word he (Pogba) says,” the former United skipper said during an appearance on 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.”
Keane’s comments were put to Pogba after Manchester United’s 1-1 draw with Chelsea on Sunday, which kept the Red Devils’ slim hopes of Champions League football alive.
However, rather than firing back at the Irishman, the £89-million man brushed off Keane’s criticism.
“Criticism from British pundits? No worries,” Pogba told French publication RMC. “They are paid to say things in front of the camera. I’m just on the pitch.
“They can say what they want, they are paid for it. I’m not paid to talk. I get paid to be on the field and fight for my team. That’s all.”
Pogba has repeatedly been linked with a move away from Old Trafford in recent weeks, with Real Madrid being touted as his next destination.
Former United midfielder Dimitar Berabatov hopes his old side retain the Frenchman’s services, recently telling Betfair: “One player people always talk about is Paul Pogba and the transfer rumours seem to swirl around him all season long.
“I hope that he will stay, because I like him as a player and as a person. I know that he is capable of much, much more and I know he wants to show that in every game and sometimes it doesn’t work. That happens to every player though – it definitely happened to me.
“Sometimes people criticise too much and it can get personal and not constructive at all.
“In the end, when that happens, it can push a player out. And when you have a club like Real Madrid, coached by a Frenchman, then I can see why Pogba might be asking questions.
“But the worst thing for United would be to let Pogba go and see him flourish at Real Madrid.”
Pogba and his Red Devils team-mates will be back in action on Sunday afternoon, taking on the already-relegated Huddersfield at the John Smith’s Stadium.
