Amorim will still want a few more players to complete his squad before the official start of the competition. Bryan Mbeumo could be one of the good signings for Amorim, he will not need adjustments to the Premier League's tough competition. It's just that United still needs to bring in players, especially for the attacking sector, which I think Amorim is still not satisfied with the existing players.
I think the Portuguese manager knows he needs a finishing forward. That's why he might consider bringing in his former pupil, Swedish forward Gyökeres. If they sign him, they won't face any major problems going forward. However, Manchester United still has defensive issues. They need to strengthen their defense, and I don't see them making any major strides in that regard.
There are many issues with Manchester United in last few years which they needed to be fixed before start of next season if they are looking for better results because if they fail to keep things on level surely they are going to face issues again which can prevent them from having better results.
Victor Gyokeres is going to be good, but now he is set for Arsenal, and they are also having their good option which can help them for having better results Bryan Mbeumo now they need to be had defensive problem which is also needed to be fixed. Time is running out if they fail to have required changes surely this is going to be not positive for them with their performance is also going to be not improved in coming season.
