Barcelona thrashed Osasuna 4-0 on Sunday.

Ferran Torres notched a brace while Ousmane Dembele claimed a brace of assists in a game of ruthless cutting edge from the Catalans, having failed to convert any of their chances against the Turkish side only 72 hours before.

In defence, it was also a special occasion for Gerard Pique, as the Barcelona icon made his 600th appearance for the club.

It didn't take long for the home side to open the scoring and help Pique to celebrate, with Ferran converting from the spot inside a quarter of an hour after Gavi was bundled over inside the box.

He added a second only seven minutes later as Dembele set him through with a finely-weighted pass for Ferran to slot underneath Sergio Herrera in the Osasuna goal.

Dembele would add another assist, making him the team's joint-most prolific assist provider this season, as he set up Pierre-Emerick Aubameyang before the half-hour mark.

The Frenchman cut back on himself on the right flank and played a cross into the path of the former-Arsenal man as he prodded the ball into the back of the net.

Rounding off the win was substitute Riqui Puig, who followed up on his own shot from distance to add a fourth for Barcelona.
