Superclasico Quiz: Did these players play for Boca Juniors or River Plate?
For the first time ever, fierce Buenos Aires rivals Boca Juniors and River Plate will meet in the Copa Libertadores final - South America's most prestigious club trophy
Ahead of the first leg of the Superclásico final, we've thrown together a quiz based on some of the two clubs' former (and in some cases current) players.
We've included 18 players altogether, some more well known than others, and want you to have a stab at working out if they played for Boca or River. Be warned, though: a couple of the names featured played for both.
Simple enough, right? As ever, we wish you the very best of luck...
