Kylian Mbappe marked his return from injury with a goal as Paris St-Germain took control of their Champions League last-16 tie against Real Sociedad.
The French champions have an underwhelming record in the competition and were enduring a frustrating night until Mbappe pounced.
Having missed his side’s previous match with an ankle problem, Mbappe scored at the back post after a corner.
Bradley Barcola added the second with a lovely finish past Alex Remiro.
Real Sociedad keeper Remiro had earlier denied Mbappe a second when he tipped his attempt on to the crossbar.
PSG, who have never won the Champions League, were far from their best in the first half and Real Sociedad’s Mikel Merino hit the bar just before half-time.
Mbappe has been directly involved in 38 in 30 appearances for his club this season – 31 goals, seven assists – the most of any player in Europe’s big five leagues.
In addition, he has now scored 44 times in 68 Champions League appearances for Monaco and PSG.
Bayern Struggle Continues
Elsewhere Harry Kane, Thomas Muller and the entire Bayern Munich team fired blank as Lazio recorded a crucial 1-0 win in their last-16 first leg match
As well as trailing to Lazio going into the second leg in Munich on 5 March, Bayern are also out of the German Cup having been stunned by third division Saarbrucken.
Kane already missed out on a trophy in his first game with his new club, when they were hammered 3-0 by RB Leipzig in the German Super Cup.
Defeats to Leverkusen and Lazio in the space of five days also represent Bayern’s first back-to-back losses since December 2019, when Hansi Flick was caretaker manager.
The Lazio loss is his 10th in 43 competitive matches as Bayern coach, already as many defeats as his predecessor Julian Nagelsmann suffered in 84 games in charge.
Bayern have been eliminated on the past seven occasions they have lost a Champions League first leg, a run going back to 2015.
