Paris Saint-Germain seemingly have one foot in the UEFA Champions League quarter-finals after claiming an emphatic 4-1 win over Barcelona at the Camp Nou on Tuesday night.
Barca made five changes, with Gerard Pique, Jordi Alba, Pedri, Ousmane Dembele and Sergino Dest all recalled while PSG made two alterations, with Marco Verratti and Alessandro Florenzi returning but Neymar was unavailable to face his former side due to a groin injury.
Antoine Griezmann had the first big chance in the 14th minute after a through ball by Lionel Messi at the near post but he was denied by shot-stopper Keylor Navas.
Mauro Icardi had a wonderful chance for Mauricio Pochettino's charges four minutes later in one-on-one with goalkeeper Marc-Andre ter Stegen, but he fluffled his opportunity, allowing the Barca defence to recover and clear danger.
The hosts were awarded a penalty just before the half-hour mark after Layvin Kurzawa brought down Frenkie de Jong inside the box and Messi fired the spot-kick into the top corner to send Barca ahead.
Mbappe quickly levelled matters for PSG in the 32nd minute with a clinical strike at the near post after a flick by Verratti.

With PSG creating the better chances in the second half, Mbappe eventually gave the French side the lead in the 65th minute with a blasting strike inside the box from a rebound after a cross by Leandro Paredes.
Moise Kean finally gave Pochettino's men a two-goal cushion 20 minutes before time with a header at the far post after getting on the end of Paredes' set-piece.
Mbappe completed his hat-trick five minutes before time with a smashing strike on the edge of the box to extend PSG's advantage, which will see the side head to the second leg with four away goals.
