Lionel Messi missed a penalty but Kylian Mbappé scored a 94th-minute winner as Paris Saint-Germain beat Real Madrid in Paris.
The quiet first half was dominated by PSG and Real Madrid were restored to their majority, but neither team was able to get the result in a 0-0 draw at half-time.
PSG had a good chance to take the lead just hours after Dani Carvajal dropped Kylian Mbappé in the box, and the referee pointed to the spot.
Lionel Messi was up but his little effort was well saved by Thibaut Courtois, and it remained 0-0.
Neymar has returned from injury with the PSG bench closed, but it looks like he has not been able to promote the winner, and the tie will have to be fixed in Madrid.
Only Kylian Mbappé will appear in the fourth minute of extra time with the winner late to raise the roof of the Parc des Princes.
