Don't want to be too arrogant about Man United's first victory, I don't know whether it will really improve with the dismissal of Ten Hag or will continue to worsen in the hands of R.V. Nistelrooy, Man United must find players who are better than the players after Ten Hag left because it will later be a boomerang for Man United, in my opinion the players brought in by Ten Hag did not make any impact for Man United, in fact they get a fairly large salary but do not contribute to winning every match, maybe all supporters of R.V. Nistelrooy who currently serves as the head coach of Man United can bring Man United to their top caste in Europe and the Domestic League.
Manchester United is likely to improve under new management. Ruud van Nistelrooy had an impressive performance against Leicester City, where Manchester United got all three points. This result suggests that the players are not the problem but the former manager was. The players are talented and of high quality. A major overhaul may not be necessary, they should instead buy more players in key positions to strengthen the squad. I am confident that a new manager can make United better than it was under Erik Ten Hag.
You are right mate, there are a lot of good coaches out there that will be able to work on the team and transform it to a high level of performance, that should have been an option instead of giving Ten Hag a long time before sacking him. Ruud van Nistelrooy will put in the best he can in order for him to improve the team performance and manage the players properly with the skills in him, because if he wants to sell himself out to the world that they can rely on him as a good coach in future. I hope to see more positive results in Manchester United upcoming matches.
