Ten Hag added many actors to the cast. Anthony came especially of his own accord and we all see how unsuccessful he is now at Manchester United. Amrabat is also one of the players who is not productive. If you say so, he had a terrible year considering his transfer budget. I don't think they will succeed under Ten Hag. Manchester United should first change the coach.
Manchester United has ensured that if ten hag's position is still very secure as a coach, currently of course Manchester United has given full confidence to ten hag to re-build their squad next season, although actually the squad they have this season has spent a lot of money on them for build in the last two seasons, ten hag has previously asked Manchester United to bring in some of his mainstay players while still coaching Ajax such as Antony and Martinez, although both were bought at a fairly high price, but Antony was not able to deliver the performance they had hoped for so far, as well as other players who were mostly requests and also Ten Hag's choice to fill the current Manchester United squad but strangely ten Hag continued to blame his squad poor performance when they suffered defeats and failures this season.
I think what you said is true, it shoulder if Manchester United is looking for another coach who is indeed better and able to lift Manchester United performance than keeping Ten Hag, I don't know what Ten Hag has been thinking all this time which is indeed very difficult to admit his own mistakes in coaching but is quite proud to consider himself great when Manchester United won the FA trophy, this season Ten Hag continues to blame each of his players when they lose every game and even player injuries are the reason they failed to penetrate the Champions League zone this season, without wanting to correct their training patterns that often make players injured.
