Lionel Messi, Barcelona
WhoScored rating: 9.14
Messi is the man out on his own at the top of our list - he's the only player in the competition to average above nine in all his games.
Despite that, this campaign hasn't been exactly straight-forward for the great Argentinian.
Injury restricted him from doing much about Bayern's steam-rolling of Barcelona last season and this time round he's only managed three games - but that couldn't stop him from finding the back of the net an incredible six times.
Now he's back to full fitness and firing on all cylinders; he became the all-time goalscorer for a single club in Spanish football with his double against Rayo Vallecano over the weekend.
Barcelona, who aren't exactly at the top of their game at the moment, face an on-song Manchester City in the last 16, so much will depend on Messi if the Catalan side are to progress.
