Tonight, two of Italian football's heavyweights meet again in the San Siro for the Derby della Madonnina - or the Milan derby, to us monolingual troglodytes at FourFourTwo.
Every since the early 20th century, Inter and AC Milan have jostled for supremacy. Originally one club, they split over a dispute of whether international players should represent the club - hence why some members of Associazione Calcio Milan left to form Internazionale.
But despite the tensions over the years, a number of players have represented both Milan and Inter - quite unusual for local rivals who are both so successful.
This is a pretty difficult quiz, we won't lie to you - but there are still loads of names that you'll be certain to know. As a clue, that lanky-looking fella in the photo above might be on the list. Give it a try, anyway.
