The Arsenal Four
Like Vermaelen, Overmars swapped North London for Catalonia.
Like Vermaelen, Overmars appeared to be in his prime when he arrived at Barcelona.
The Dutch winger won nothing in Spain, despite costing Barca a whopping €30 million.
Emmanuel Petit moved along with Overmars, and is another example of a player whose career took a turn for the worse when opting for the Nou Camp over Arsenal.
Alex Hleb could also be added to this slide—a list in itself.
The Belarusian left Arsenal for €21 million in search of glory. He made only 19 La Liga appearances before leaving permanently in 2012 for…er…Krylia Sovetov Samara.
Wenger 4 Barca 0!
