Ousmane Dembélé's injury troubles returned at the worst possible moment as the Paris Saint-Germain forward was forced off the pitch after only 20 minutes during the club's UEFA Champions League encounter against Barcelona.

The reigning Ballon d'Or winner had barely settled into the contest before he limped off, raising fresh concerns about his fitness heading into a pivotal stage of the competition.

Dani Olmo was also withdrawn early in the match for Barcelona, leaving both sides without key attacking figures for large portions of the tie.
