Since Sir Alex Ferguson's retirement as manager of Manchester United in 2013, the team's performances have not been as successful as they were during his tenure. since his departure, the club has struggled to find consistent success and has failed to maintain its former dominance in the title race.
Manchester United's current situation is deplorable. Even though ManU's squad has suffered a massive erosion, I think the main problem is the manager. Erik ten Hag is a manager who has never been able to settle and press the opposition. I find it hard to understand his game plan, maybe he can create a very good transition team, but it's definitely not for ManU. When you think of ManU, the system of play that Sir Alex Ferguson has created over the years makes us not accept the current situation. Unless ManU bring in someone with a big vision and the mentality of a big team manager, it is impossible to recover.
Since Sir Alex Ferguson left the club, Jose Mourinho is the only manager that came close to making the club great again. Unfortunately he didn’t received much support from the club owners. Mourinho did not receive the kind of support that has been given to Erik Ten Hag. They refused to get him the players he wanted, and when problems arose between him and some of the players (Pogba and Martial), the club was quick to defend and take sides with the players undermining the authority of the manager.
Everything Mourinho complained about was true right and it's proven now. It would have been a very different story if Mourinho was the manager when Christiano Ronaldo returned to Manchester United. Manchester United made a huge mistake to sack Mourinho. And yet they are giving ETH more time to manage the club.
Under Mourinho Manchester United can gets Europa League trophy and this is the last trophy for Manchester United from European competitions because since that Manchester United was unable to gets the trophies from Europa League or even champion league but after 2 years became an the manager of Manchester United unfortunately Mourinho have to sacked because on 2018 Manchester United have to finish at 6th place which at that time the owner has considers Mourinho was failed to bringing this team to finish at champion league zone
Talking about Manchester United previous managers besides Mourinho i think we shouldn't be forget about Ole Gunnar Solskjaer because similar to Mourinho Solskjaer also didn't supported with huge money and although under him Manchester United didn't gets the trophies but they can able to finish at runner up position and some people are still believe if Solskjaer didn't sacked and still train Manchester United until now probably this team has been change became an strong contender for Manchester City for race title
