Andreas Christensen headed the winner as Barcelona beat Paris Saint-Germain 3-2 at the Parc des Princes in Wednesday's first leg of their Champions League quarter-final tie.

After falling behind to a Raphinha goal, PSG struck twice early in the second half through former Barcelona forward Ousmane Dembele and Vitinha to take the lead.

Raphinha equalised for Barca with his second goal of the night before Christensen nodded in from a corner in the 77th minute.
