How could Manchester United be negotiating for Mbeumo for over 50 days now and the deal is not completed yet and they are talking about Jackson. What is wrong with Manchester United and who told them that it's only English teams that will produce a good striker for them. Manchester United scout should look beyond England and buy a young and hungry striker.
They actually asked for Gyökeres' price and talked to the player also. But they got a negative answer from him. He prefers Arsenal over them which is understandable.
Manchester United should have lifted that Europa League trophy. A CL ticket is very effective on bringing this kind of players easier.

Now on Mbeumo... I'm only having doubts if he could just be a seasonal scorer. His performances in earlier seasons were much worse.
Same is said for Gyokeres too, he was a prolific scorer at sporting, but before that he wasn't a good scorer at all. Because of this, there were a lot of people who doubted he worths this much. In any case, Mbuemo should be helpful for Manchester United considering how terrible they are, he doesn't have to be some superstar, he just needs to be "decent" and he would still be one of the best in that team.
However, he definitely doesn't deserve the 70 million offer that they got, he is good but not THAT good, United definitely got taken to cleaners on this transfer. Considering how much they already spent, and time they used, I am pretty sure they are not going to have that many more transfers done rest of the summer, not big ones at least.
