Paris Saint-Germain seized the advantage in their Champions League semi-final against Arsenal as Ousmane Dembele sealed a 1-0 win in the first leg on Tuesday.
Dembele struck in the opening minutes at the Emirates Stadium and Luis Enrique's side held on to the lead with a composed display that kept Arsenal at bay.
PSG will head into the second leg at the Parc des Princes on May 7 as favourites to reach the final against Barcelona or Inter Milan as they look to win the tournament for the first time.
But the French champions should take nothing for granted given their history of epic European collapses.
