As adidas reveal their 18th Champions League Final match ball, we've half-volleyed one down memory lane, rustled around in the bushes behind the goal and picked out every adidas ball to take centre stage in the biggest club match in world football.

On the week that the knockout stage commences adidas have unveiled the ball that will be used right up through to the 2018 Final in Kiev, Ukraine. There's history in those trademark stars, dating right back to 2001 when adidas took over from Nike as the UCL official match ball supplier. With the stars progressing to represent the host city of the final, we're starting from back when to see how things have shaped up.
