Manchester United management has been in the process of rebuilding Manchester United for a long time, and if they were serious about rebuilding Manchester United, they could have achieved that a long time ago, and Manchester United could have even won the Premier League title in the past seasons. If you say Manchester United is a club that doesn't give a coach all the time he needs to build up his team, that means you don't know Manchester United very well because among the big clubs in the Premier League, Manchester United is the only club that allows a coach to have all the time he needs to build a team.
Hah, buddy you very funny. You speak like you dont watch football often or you a passionate fan of Manchester United. If it was that easy to win the trophy why haven't they done that. Manchester United thought the problem has to do with coaching, they changed their managers from Ten Hag to Amorim and still couldn't win a final against Tottenham the most confused club currently in EPL. Now they think its the players they have to change, but the sad truth is no player who wants to win a trophy will agree to move to Manchester United.
They didn't win the Premier League before because Manchester United's management couldn't find a coach capable of winning the Premier League. Manchester United's management made a lot of money available for the coaches to hire whoever they wanted. The thing is, the coaches made terrible signings for very high prices.
Now Ruben Amorin has arrived. He might be able to make Manchester United a winner again, but he needs time to put together a good squad. He came when the current squad was already assembled.
