1. Robin van Persie
When Thierry Henry left North London, he left them with massive shoes to fill. Unfortunately for Wenger, he tried to sign many a player in that position to no avail. The likes of Emmanuel Adebayor, Nikolas Bendtner, and Marouane Chamakh all failed, until one talented Dutchman finally came good. It’s no secret that Robin van Persie had many injury problems at Arsenal, but it was in the 2010/11 season where he scored 37 goals in 48 apps finally repaying Wenger’s faith in him.
However, van Persie would allow the accolades to get to his head and demand a move away from the Emirates. The Dutchman would engineer a move for himself to Old Trafford and he would be justified in his decision, as he won his first-ever Premier League title within the first year at Manchester United. That alone was enough for Van Persie and he has openly said he doesn’t regret leaving London purely for the fact that he has a PL medal in his cabinet.
