Lionel Messi is undoubtedly one of the best players on Earth, but he's not having a great season at PSG. The Argentine has struggled to play regularly and he has only scored seven goals in Paris so far - twice in Ligue 1, five times in the Champions League.

That's why all the eyes were on him ahead of the round of 16 tie against Real Madrid, with the soccer community eager to see if Messi stepped up against one of his favorite victims.

However, it's been a long time since he scored against El Merengue and he missed out on a great opportunity to end the drought. In the first leg of the UCL round of 16, Thibaut Courtois denied Messi's spot-kick.

It's not a secret that Paris Saint-Germain aim to become European champions for the first time this season. But the knockout stage brought them a challenging task from the very beginning by drawing them with Real Madrid.

After an uneventful first half, Mauricio Pochettino's men started to put the visitors' back against the wall. But Courtois has firmly stopped any effort from the hosts so far, including a penalty kick from Lionel Messi.
