Pochettino's men boast a 1-0 lead from the first leg, but the French giants could be without their marquee attacker on Wednesday.

PSG are gearing up for a highly-anticipated UEFA Champions League showdown with Real Madrid, with the Ligue 1 giants set to visit Santiago Bernabeu for the second leg of their round of 16 clash. The French heavyweights boast the advantage, but in a huge blow to their hopes of progressing, one key player has reportedly picked up a knock.

The first leg of their knockout stage encounter took place at the Parc des Princes, with Pochettino's men triumphing 1-0 at the death. Despite dominating possession and creating the better chances, the French top-flight side were forced to wait until the final minute for the winning goal.

After Lionel Messi's second-half penalty miss, PSG appeared destined for a draw. That was until Kylian Mbappe popped up with a brilliant moment of magic, beating two men to slot the ball past Thibaut Courtois a minute before full-time to secure the victory.

However, there is a chance the 2018 World Cup winner might not be available for the second leg, as reports have emerged claiming Mbappe picked up a knock during training for Wednesday's showdown. This is according to RMC, as per Get French Football News, with the French news outlet claiming he's set to undergo medical exams 48 hours ahead of the 2nd leg fixture.

Will Kylian sit out the trip to Madrid? Only time will tell, but this is a worrying development for PSG as they aim to avoid an early exit from Europe. The 23-year-old is the club's top scorer, and by a mile, netting an impressive 24 goals in 34 outings. His worth was laid bare for all to see in Les Parisiens recent outing, a 1-0 defeat away to Nice. The former Monaco sensation was left out of the squad, with the likes of Messi, Neymar, and Di Maria failing to threaten the opposition in Mbappe's absence.
