Ruben Amorim is really trying his best in the transfer window to strengthen Manchester United's squad so that Manchester United can be able to compete in the Premier League next season, but Manchester United's financial problem is limiting Ruben Amorim from going for a quality striker that will be reliable and help Manchester United to win matches and compete in the Premier League next season. Manchester United has ruled out any possible move for Jackson and Sesko, and as it stands now, nobody knows the striker Manchester United is going to sign this season.
I don't think financial problems are what's making it difficult for Manchester United to sign quality players. It's their lack of European football. Top players don't want to play for a club that won't play Champions League football next season and still have no clear hope of playing it the season after that.
A player like Isak has shown interest in leaving, but Manchester United cannot approach him, not because they don't have the money, but because they know he won't want to join them when there are so many options out there and quite frankly, at the moment, it's better to remain at Newcastle.
Money isn't Manchester United's problem, they spent 75 million for Mbuemo, if they want to, they can spend 100 million on a player, but will that player be willing to join them/
What I think United should do now is just focus on getting players that can make them compete. They have to be in the top four next season. If they can get a decent striker that can give them 20 goals and get decent midfilers before the transfer window closes, then they can work from there.
