If Manchester United does not do that I do not think they can rise, now Manchester United is very depressed or far behind so if they want to realize their target to compete at the top then there must be a big step taken by Manchester United management, otherwise there will be no significant change.
Osimhen is a very qualified player and I think he will be very helpful for Manchester United in the front line, but the current obstacle is because of finances, so Manchester United must solve this problem first before building a team and I think there are many ways they can do it, namely by making exchanges and selling some players who are not included in the plan for next season.
This Manchester United under Ruben Amorim, they could still buy players with less transfer fees which will still give a great performance to the team by next season. All they need is overhauling this current squad.
Sometimes it's about the quality and skillful disposition of the coach in managing the players before him. Perhaps, they could get Victor Osimhen as the only expensive player since they desperately need a good top 9 to boost the squad, then they can get in other positions lesser fee quality players.
Man United looks less aggressive in this transfer market because so far they have only signed Cunha alone. It is likely that they are still waiting for some of their players to sell first so that they have additional budget that they can use. Man United's front line has been really problematic in the last 2 seasons, so they really should be looking for a new striker. Osimhen is a good option, as is Gyokeres, but for either of those two strikers, Man United really needs to prepare a big budget.
It will be interesting to wait and see whether, when the transfer market reopens again, Man United will get a new striker, or they have to wait for Hojlund or Zirkzee to be sold first.
Gyokeres is not interested in coming to Manchester United from the news that I read this morning. I believe that Amorim is working on something and will definitely sign new players to replace the ones leaving. Of course, the players that they are offloading should be sold so that there will be funds to sign new players easily.
