A failure to sign Paul Pogba could lead to an unhappy dressing room at Manchester United, Rio Ferdinand has warned.

It was gathered Jose Mourinho’s side are set to sign the midfielder form Juventus for €110 million, though a deal is yet to be completed. United were thought to be keen on striking a deal before Sunday’s Community Shield against Leicester City, but they are yet to make a breakthrough. And Ferdinand is concerned that United players who have been expecting to line up alongside Pogba could become disillusioned if the deal is not done. “As a player in the changing room, you’ve been thinking for so long: ‘He’s coming, he’s coming’,” Ferdinand was quoted as saying by The Independent. “If he doesn’t sign it could have an adverse effect mentally on the players in the changing room. For a short period of time at least. “It’s important they sign him.”
