Paris Saint-Germain (PSG) may have to face Arsenal without star winger Ousmane Dembele in the second leg of their UEFA Champions League semi-final.

Dembele, who scored the only goal in PSG’s 1-0 win over Arsenal at the Emirates Stadium, left the game in the second half and was replaced by Bradley Barcola. Although he didn’t seem injured at the time, PSG manager Luis Enrique later confirmed that Dembele has a small hamstring issue.

Enrique said that medical tests will be done soon, but Dembele could miss the return match in Paris next Wednesday.

“It’s nothing serious, but there is still some doubt,” Enrique told reporters after the match.

He added, “We are a strong team. If Ousmane plays, that’s great. If not, the team will still be ready.”

PSG currently hold a small advantage going into the second leg thanks to Dembele’s goal.
