Lionel Messi backed up his Clasico heroics with two more goals as Barcelona dispatched lowly Osasuna 7-1 to pile further pressure on Real Madrid in LaLiga's title race.
Messi capped a virtuoso individual display with an injury time winner at the Santiago Bernabeu on Sunday, moving Luis Enrique's men back to the top of the table on goal difference.
75 min: FYI: Barça's 4th goal, which was also 's 33rd of the season and 502nd of his career, was Barça's 150th this season! April 26, 2017
A deep-lying Osasuna gave little away during the opening 10 minutes but, shortly after venturing into the Barca area for the first time, a dreadful error saw them go behind on the break.
Fausto's pass on halfway was slack and Messi did not need a second invitation, intercepting the loose ball, nodding it down and juggling it before lifting a finish over goalkeeper Salvatore Sirigu.
Camp Nou rose in acclaim, with a number of fans replicating Messi's already famous weekend celebration in Madrid by holding their Barcelona shirts aloft.
It remained a patience game for the hosts until their second arrived with half an hour played, after Messi found space 25 yards from goal to see a whipped shot deflected narrowly wide.
The resulting corner was taken short to Ivan Rakitic, whose bouncing cross was greeted by an assured right-footed finish from Gomes.
Torres stunned Camp Nou by reducing the arrears three minutes into the second half.
The midfielder's free-kick was nicely struck but questions will be asked of Barcelona goalkeeper Marc-Andre ter Stegen, whose initial movement to his left – behind his defensive wall – left him with no chance.
Sirigu pushed a header from Mascherano on to his post as Barca sought to restore their cushion, but Torres had an equaliser in mind when he fired goalwards and Ter Stegen stood firm.
Any jitters among the home faithful were settled in the 58th minute when Gerard Pique took down Rakitic's left-wing corner on his chest, shot against the base of the post and saw Gomes slot in the rebound.
Following that simple finish, Messi then demonstrated the brilliance he makes look routine by dropping deep to receive possession, scampering towards the edge of the box and caressing a left-footed shot into the corner.
The five-time Ballon d'Or winner then departed to a standing ovation – the pressure well and truly back on a Madrid side who have seen quite enough of him this week.
Barca continued to enjoy themselves in their talisman's absence, with Alcacer sliding to lift a finish over Sirigu after Osasuna failed to deal with Arda's hopeful 65th-minute ball into the box.
Merida clumsily tripped Denis Suarez to give Mascherano the chance to finally become a Barcelona goalscorer in his seventh season with the club. The Argentine clattered the ball high into the net, prompting huge cheers in the stands and hysterics on the home bench.
500 - Javier Mascherano has scored the 500th goal for Barcelona under Luis Enrique in all competitions. Milestone. April 26, 2017
Alcacer then steamed clear to coolly round Sirigu and completed the rout four minutes from time, sending a resounding message to Zinedine Zidane and company.
