Paris Saint-Germain have cruised to a 4-0 victory over Bayer Leverkusen in the first leg of their Champions League last 16 match at the BayArena.

The visitors took the lead in the third minute of the match through Blaise Matuidi, who was played into the box by Marco Verratti before sliding a low effort past Bernd Leno.

Sidney Sam had a half-chance to respond for the hosts, but after being picked out in the box by Andres Guardado he fired wildly over the bar.

PSG almost scored a second goal soon after when Zlatan Ibrahimovic latched on to a weak punch from Leno and saw his close-range effort blocked on the line by Roberto Hilbert.

In the 39th minute the visitors were given the opportunity to double their lead after Emir Spahic brought Ezequiel Lavezzi down inside the box and the referee pointed to the spot.

Ibrahimovic stepped up to take the resulting penalty and made no mistake to place the ball past the keeper and into the bottom corner.

PSG scored their third of the evening four minutes later, when Ibrahimovic fired an effort into the top corner after being teed up by Matuidi.

Leverkusen were reduced to 10 men just before the hour mark as Spahic picked up his second yellow card of the evening.

PSG thought that they had scored a fourth when Matuidi's curling effort took a deflection of Philipp Wollscheid before finding the net, but it was disallowed because Lavezzi was standing in an offside position.

With two minutes left to play Yohan Cabaye fired a strike into the top corner following Lucas Moura's pass, to give the visitors a comfortable lead ahead of the second leg in Paris.
