Ousmane Dembélé (27) has given a hint as to the gravity of the hamstring injury that he sustained during Paris Saint-Germain’s 1-0 win over Arsenal in the first leg of their UEFA Champions League

Dembele had another decisive showing in London, spearheading PSG past the Gunners and giving his side a slender advantage going into the second leg in Paris next week. However, eyebrows were raised when the 27-year-old left the pitch in the 70th minute. Dembele’s departure immediately drew concern that he would be unavailable for the second leg.

Ousmane Dembele scored early and Gianluigi Donnarumma saved often as PSG took control of their UEFA Champions League semifinal tie with a 1-0 win over Arsenal.
