SAN SEBASTIAN, March 6 — Kylian Mbappe lethally fired Paris Saint-Germain into the Champions League quarter-finals with a brace in a 2-1 win at Real Sociedad yesterday, his team cruising through 4-1 on aggregate.

Coach Luis Enrique has slashed Mbappe’s minutes in recent weeks after the player told the club he would leave at the end of the season, but the France captain proved he will be vital if PSG are to finally win the competition for the first time.
