Does Manchester United's decision to retain Ten Hag have anything to do with the victory achieved in the FA Cup? This success also means that Manchester United will play in the Europa League next season. If judged from achievements in the Premier League, Ten Hag has failed to make Manchester United a club that is ready to compete in the top four, so there is no reason for Manchester United to continue working with Ten Hag.
It doesn't seem like they managed to win the FA Cup, because the decision to keep Ten Haag happened indirectly when they won because United reportedly had talks with Thomas Tuchel but the talks didn't continue after that United announced they were going to keep Ten Haag, it looks like they didn't have any options better than keeping Ten Haag.
Ten Haag always blamed injuries to his players for United suffering bad luck last season, but that also happened because he didn't have enough expertise in maximizing his reserve players.
Whether or not Ten Hag will coach Manchester United next season is appropriate, only the club's board of directors will assess it, but the news currently spreading is that Ten Hag is still trusted to lead Manchester United next season. Many parties from outside the club began to regret this decision because there were doubts about his ability to take Manchester United in a better direction, these doubts arose after Manchester United failed to compete in an elite position this season.
Management always knows what is best for the club but they can make mistakes in appointing the head coach.
United will start from scratch next season, several senior players are rumored to be leaving the club and there will definitely be some updates to their squad but that is not a guarantee that something better will happen to them, raising United to be a team at the highest level is not easy, it is proven that several coaches have failed here since Sir Alex no longer coaches United, and maybe the next one is Ten Haag, maybe they can become champions but not the English Premier League champions.
