There was no chance of Luis Enrique substituting Kylian Mbappe at halftime of Tuesday's Champions League encounter.

Mbappe extinguished Real Sociedad's hopes of a second-leg comeback in the round of 16 with two excellent goals in northern Spain, leading Paris Saint-Germain to a 2-1 win and 4-1 victory across the two fixtures. The forward appeared unburdened by reported tension with his head coach since his minutes were slashed ahead of an expected summer switch to Real Madrid.

After an aggressive and daring start from the hosts, Mbappe put PSG in full control after he sprinted after a pass, eked open space with some speedy footwork, and forced repairs to the net after firing in from an acute angle.

For his second goal, Mbappe hung off the last man to stay onside before latching on to Lee Kang-in's lofted pass. He ran with the ball and shaped his body to pick out the far corner before slotting home at Alex Remiro's near post.

"I don't have any message in particular. I just always want to play in the Champions League. It is a very important competition," Mbappe told Canal Plus post-match.

"I try to always perform. Sometimes that happens and sometimes it doesn't, but I will never be a player who hides."

Mikel Merino scored a late consolation for Real Sociedad.

Overall, it was a straightforward progression to the quarterfinals for Paris Saint-Germain - not something you'd usually associate with the serial Ligue 1 winners. And perhaps most promising of all, PSG advanced with the youngest starting XI (23 years and 361 days) that they'd ever fielded in the competition.
