He said in a TikTok chat [via Daily Mail]:"I'm not bothered about Pogba's comments to be honest with you. I think that once a player has left, he can say whatever he wants. Fine, no problem. But I don't think he has performed well over the last six years. I don't think the club have performed well with him either, or handled him well."He continued:"It's been a partnership that, to be fair, has failed on both sides so that is what you'd have to say on that one. There is no winner when a player leaves after six years with the money that has been spent and very little has been won."He further added:"The player leaves dissatisfied and the club are dissatisfied with it as well. It leaves a bad taste in the mouth because it's the second time it's happened."Pogba played 232 times during his second spell at Manchester United, registering 39 goals and 51 assists, and winning two trophies. He helped then head coach Jose Mourinho lift the UEFA Europa League trophy and the League Cup crown in 2016/17.Last season, he scored just one goal and provided nine assists in 27 appearances for the Red Devils across all competitions.In his new Amazon Prime documentary titled 'The Pogmentary' [via The Athletic], Pogba cleared the air about his departure. He said:“My thought process is to show Manchester [United] that they made a mistake in waiting to give me a contract. And to show other clubs that Manchester [United] had made a mistake in not offering me a contract.”ESPN UK@ESPNUKManchester United have let Pogba leave for free ... again 2012: Paul Pogba joins Juventus for free 2016: Paul Pogba joins Man United for £89m 2022: Paul Pogba joins Juventus for free6961460Manchester United have let Pogba leave for free ... again 👀⚫ 2012: Paul Pogba joins Juventus for free🔴 2016: Paul Pogba joins Man United for £89m⚫ 2022: Paul Pogba joins Juventus for free https://t.co/eq78EmgwLhHe also said:“How can you tell a player you absolutely want him and offer him nothing?
