Just 16 teams remain in the UEFA Champions League, each of them returning to action this week as the road to the final in Budapest continues.

Having talked revenge all week, PSG started the game with the appropriate energy and impetus, though it were Chelsea who had the first chance: João Pedro not quite able to steer a Cole Palmer cross on target.

PARIS (AP) — Chelsea's Pedro Neto apologized for shoving a ball boy late in his team's 5-2 loss to Paris Saint-Germain in the first leg of their Champions League last-16 match on Wednesday. The ball had just gone out of play down the right in stoppage time when the Portugal winger tried to get it quickly and shoved the ball boy in the chest as he appeared to be trying to hold onto the ball.
