Arsenal and Chelsea are rivals. But it's not the big London rivalry, despite these two being historically the two best sides of the Smoke. When Arsenal signed Sol Campbell from Tottenham in 2001, there was uproar - yet business between the red and blue sides of the capital is relatively common.
Just recently, Jorginho and Pierre-Emerick Aubameyang have gone to play for the opposite sides to those that they won trophies with. But we're not going to give you those two. That would be far too easy. Can you tell us which teams these 20 players played for... if any?
It's time to leave London and expand your horizons, charting the immense history of all English football, the truly staggering costs of global talent, and the soundtracks that defined a generation of gamers. A majestic new selection awaits, once again, courtesy of Kwizly.

Now for a look at the spectacular economics of the beautiful game. How well do you know the players who commanded truly astronomical fees?
