Sign a striker
You can imagine how dismayed United supporters are after Chelsea signed a France international goalscorer from one of the big five leagues for a reasonable fee after their worst season in nearly three decades. Christopher Nkunku was briefly of interest to United and he would have been a worthy figurehead had Chelsea not been so quick off the mark.
Instead, United could end up paying around double the £52million Chelsea have parted with for Nkunku. RB Leipzig should have had Chelsea over a barrel as Nkunku's contract still had three years to run and Chelsea have thrown money around as recklessly as schoolchildren in a food fight.
