PSG went into the game needing a win to have any realistic hope of qualifying, with Napoli having shocked both sides earlier on in the campaign.
And the Spaniard got his side off to the perfect start. He raced into the box, capitalising on some slack defending.
From there it was a simple finish, firing the ball low with his right foot and leaving Alisson for dead. The goalkeeper did not look impressed.
At that point, it left Liverpool needing a win on the final matchday, against Napoli in Liverpool, to stand any chance of going through. The Italians took an early lead against Red Star.
