I think they need to sack him,he was given too much time as a coach and didnt do anything and just shows bad rep for the club with all of his decision. After Ronaldo it goes downwards and that is a serious problem for the club. Players dont like him and that can only cause problems,he cannot replace all of the players.
Don't forget his achievements last season he managed to bring Manchester to finish in the 3rd place and that's without Ronaldo. Indeed, this season Manchester United's performance has not improved, I think Ten Hag should be given a chance until this season is over and see how Manchester ends the season. Jadon Sancho does have problems with Ten Hag but that doesn't describe all players and Ten Hag has reasons why he should do it, Ten Hag's current focus is on getting out of pressure and preparing other alternatives to overcome injuries and internal problems.
Actually, there are many people who don't like Ten Heg. But I think he deserves to be given a chance at least until this season ends. Because last season, Man United started the season badly, although not as bad as now. But from the middle of the season Man United bounced back and continued to win matches which made MU move up to 3rd place at the end of the standings.
Maybe this time the same thing will happen to the club's performance. Although I'm not sure because last season they weren't this bad. This season, if Ten Heg cannot improve the squad then MU's fate will be the same as Chelsea.
