#2 Alexis Sanchez (Arsenal to Manchester United)
The former Arsenal frontman swapped red jerseys as he went from Arsenal to Manchester United. There was plenty of speculation about where he would go, with the likes of Liverpool and Manchester City also reportedly requesting for his services. This was after City had him within their grasp during the summer, before the deal eventually fell through.
We all know that Sanchez can be a game changer within a matter of moments, even with him having a poor year (by his standards). Sanchez opened his United account with a goal in their 2-0 win against Huddersfield Town, and will look to keep putting them away as he tries to help keep United within the coveted Champions League spots.
He also has that number seven, which tends to be either a blessing or a curse. Only time will tell which it will be in Sanchez's case.
