#1 Arsenal

Arsenal have been in desperate need of star players for some time now, and although the signings of Aubameyang and Lacazette have improved their attack, there are still areas which let them down -- Jadon Sancho could be the answer to their woes.
The left flank has been weakened considerably since Sanchez's departure and needs to be filled once more with top talent. Occasionally, the likes of Alex Iwobi will step in and try to cover the role, but the fans are acutely aware of the big step down in quality because of this switch, and it's left them unhappy with the club for not recruiting well enough.
This would be a major opportunity for Arsenal to show that they mean business by signing Sancho in the summer, and by muscling out any other competition, Arsenal would prove that they have lofty ambitions once again, no longer being satisfied with a mediocre fourth place finish every year.
