Thus, it seems like it would be better for Manchester United not to involve Erik ten Hag in plans to buy and sell players in this transfer market. Because after all, if Erik ten Hag is still fully involved in choosing the players who are bought and sold, then I think mistakes will still occur which will certainly be detrimental to the team.
The manager should always be involved with buying and selling of players as he's the only one that knows the players he can get the best out of them in the season and those that are not going to be useful to him. Giving managers your own players will not make it possible for him to be capable of coaching the team very well. The manager will always have players that he believes he can work with very well as they'll be listening to him and oykay for him therefore those are the players that he should be using to play almost every game and get the best result for the team. The board should allow the manager and not get involved.
