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.
Erik Ten Hag even if he fails to qualify Manchester United for the Champions League next season would still not be sacked no matter how they do it.
The club has said they will support his decisions to get a new defending defender to support the defense since Lisandro Martinez has been brutally Injured and that energy and aggression he brings into the squad is no more.
Ever since Lisandro Martinez got Injured during the game against Sevilla, Manchester United defense has never been the same. Not even Lindelof, Harry Maguire or Jonny Evans comes close to Lisandro.
