In total, 39 different clubs have contested European Cup finals since the first one took place in 1956.
In recognition of a new Champions League campaign being just around the corner, we've thrown together a quiz in which we'd like you to have a stab at naming as many of these clubs as you possibly can.
To be clear, we're looking for any of the teams to have won or lost European Cup (or Champions League, as it's now known) finals.
You've got ten minutes to name as many of them as you possibly can and we've also kindly given you the country from which each club comes from just to help you out a bit.
Best of luck...
