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.
I don't see any reason why a coach should not be involved in the signing processes of a player because even when players are signed to the team, isn't it still the coach that will make decisions of who to feature in a game? As a matter of fact Eric Ten Haag made good improvements towards the end of last season so hopefully if he continues with that same spirit energy this new season, the team will go far this season.
Ten Haag isn't a bad coach irrespective of the fact that he started very poorly last season but he can make a difference this season considering the fact that he helped the team win a trophy last season so he should be fully involved in any decision the club want to make about signing of new players to the team.
