Liverpool legend John Barnes has urged Manchester United to sell Paul Pogba if the Frenchman is unhappy at the club.
Pogba's future has been the subject of relentless speculation in recent transfer windows, and the midfielder has again been linked with moves to Real Madrid, Juventus and Paris Saint-Germain ahead of the summer.
The 27-year-old has managed only eight appearances so far during an injury-hit campaign, and Barnes believes that the off-field headlines surrounding him have created a "toxic" atmosphere.
"You simply cannot have an unhappy player at a football club, you can't make them feel more important than the club and fans," Barnes told BonusCodeBets.co.uk.
"Equally, it can undermine the club by being disrespectful because they're not keeping the player happy. It is a ridiculous concept that you need to keep players happy.
"The players should have to keep the manager and the fans happy, and if you don't, then [Pogba] has to go. This whole situation at United, from the outside, it seems like he has so much power at the club which makes everyone talk about him, the situation is so toxic within the club. He should leave."
Pogba's contract at Old Trafford expires next summer and, while United have an option for a further year, recent sports suggest that he could be available for as little as £55m.
