Well, it seems like Erik ten Hag really doesn't have a good choice when it about to buying and selling players because after all, Donny van de Beek also came from Ajax before and it's possible that Erik ten Hag brought him too at that time. But in reality, Donny van de Beek was also a loan player until he was actually sold at this moment to Girona after previously Donny van de Beek was loaned to Everton and Eintracht Frankfurt.
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.
Erik Ten Hag has got good eyesight for players. And for your information, Donny Van Dee Beek wasn't brought into Manchester United by Erik Ten Hag. He was brought in during the time of Ole Gunner Solskjaer. Even when Erik Ten Hag came in as manager of Manchester United, his statement was that, he didn't come to meet Donny Van Dee Beek the same way he was before he left Ajax for Manchester United.
Donny was loaned to Everton? I never heard shii bout that though. I'm aware he wanted a move to Frankfurt but, what I don't know is if the loan deal happened as I didn't take note.
Manchester United never had a good sporting directors and team, now they do and even before they make a move completely for a player, they also consult Erik Ten Hag because he'll be the one managing these players. He is not directly involved you see, but he needs to be updated on in's and outings. He wants to play a possession base style of football and also proactive football when off the ball.
You'll obviously need players confident on the ball and who has technique. I'm already tired of explaining shiit lol. Harry Maguire, Aaron Wan Bisakka and a couple few players do not fit in, they need to leave.
