Oshiemen is not a kind of player Manchester united need right now, to me Oshiemn should remain in Galatasaray and complete his permanent deal. Manchester united will not play in the champions league next season and bidding for Oshiemen will cost them alot of money, its better for them to go for a player that will be willing to play foe the club and bring back the glory.
We have even seen strange arrivals in the previous Ten Hag era such as some players like Zirkzee, Antony, Onana and even Weghorst just because of the closeness in the Dutch national team or Ajax without thinking about whether the player fits or not in the Manchester United style so for now I think the situation will remain the same where the match according to the coach's style will be prioritized as before.
So whether or not we think Osimhen fits the Manchester United style when Amorim wants this player to come then he will definitely be prioritized as a new player no matter how difficult the conditions are.
On the other hand we also know that in the end Manchester United still need a striker with good goal scoring instincts so when talking about Osimhen, who is currently still quite good at scoring goals, I actually don't think it's wrong when they want to bring this player in this summer transfer.
Erik ten Hag did a horrible job at Manchester United, it took the club a long time to realize that Erik ten Hag was not a good fit for the club. ETH thought that he could Manchester United to recreate his former team Ajax with Manchester United but his experiment failed and Amorim is the one left with the broken pieces. It will take a longer time for Amorim to rebuild the team and even longer to see the results.
