The on-off saga over De Gea’s contract has taken another twist, and some sources confirmed that Manchester United are now less optimistic that De Gea will stay. But there are so many talks about a new Goalkeeper. Ten Hag is known to want a goalkeeper who is more competent with the ball at his feet, and I feel that Manchester United will likely make a new signing this summer regardless of the outcome of De Gea’s contract saga.
Also, I feel that the amount of money they will have to spend could depend on whether they are bringing in competition for De Gea or signing a new No.1 to replace him.
De Gea ended up not being included in the Ten Hag squad for next season. Man United will most likely be looking for a new goalkeeper in the transfer market this summer. and if they don't get it, maybe Ten Hag will take advantage of the goalkeeper he has. it is also possible that Ten Hag can get a goalkeeper in the winter transfer market halfway through the season.
I don't think there will be many changes in the Ten Hag squad. besides they are also trying to get a striker.
Ten Hag need competent defenders and there is still Maguire replacement on the table, they need more reinforcement to fight next season because they wouldn't be playing only just Premier league, they will be playing along with Champions League and seeing that its been a while they made it to the Champions league, then they need all the good players they could sign in this transfer window, there is no any reason to wait for January transfer window, many matches would have started by that time and if they don't serious, they risk coming home again.
David de Gea should look for another place to further his career, many A list players have left and they made names for themselves after that, he should accept the decision of the club as there is no any pending contract that bind him and Manchester united.
