Vitolo capitalised on schoolboy defending by Sergi Roberto to nudge Sevilla ahead, while Lionel Messi levelled it up on the brink of half-time before Luis Suarez sealed the victory late in the second stanza.
Sevilla established a rapid velocity and Barcelona obliged. Luciano Vietto's scuffing shot brought ter Stegen into action, while the 'MSN' activated a few seconds later as Lionel Messi and Neymar helped shuffle the ball to the overlapping Suarez on the left, however the Uruguayan was denied by a defiant Sergio Rico.
Jorge Sampaoli's team enforced a plethora of attacking options and committed both full-backs forward to creating width in behind Barcelona's evidently weakened defence. Escudero, occupying the left flank, exploited 'false' right-back Sergi Roberto who endured a difficult trip to Manchester City in midweek, but he was unsuccessful in his attempt of converting Mariano's cross into what would've been an exquisite volley.
Sevilla landed the killer blow, to the dismay of Sergi Roberto at fault. The full-back was sitting too deep on his own and he failed to intercept a through ball which allowed Vitolo to scamper in behind the nonexistent backline and dink over the advancing ter Stegen.
Barcelona's best chance came minutes later, as Sergi Roberto's dangerous cross bounced off several bodies before Lionel Messi scuppered the chance with a dismal strike from the edge of the box.
In many ways, Enrique's renowned style of building from the backline was the architect of the issues created, as Sevilla's capitalisation on wayward passing culminated in failure to track markers, and the visitors were fortunate to remain 1-0 down when Vitolo blootered his effort wide after Sarabia effortlessly danced within the six yard box in acres of space.
Yet moments later, Barcelona's star quality shined through the bad patches and Lionel Messi brought his side level on the brink of the interval. Neymar scampered down the left flank, cut inside, then dinked to his teammate Messi who clinically finished from the edge of the area.
Moments later, Adil Rami saved his team from falling behind as Barcelona's attacking starlets went to work. Suarez scampered through acres of space, then squared across to Lionel Messi on the overlap however his shot was blocked by the Sevilla defender who intelligently closed the distance and stuck out a leg in time. blocked his attempt on goal.
Luis Enrique's title-chasing team were superior in speed and attacking movement, though the hosts did remain a menace on the counter attack and Javier Mascherano was luckily switched on to combat Vietto's storming run and snuff out the danger.
Defenses opened up, space was easier to exploit, and the elite force of Barcelona capitalised to make it 2-1. Initially, Messi illustrated his class by dropping the shoulder, dribbling through three defenders. His shot bundled over the crossbar, though, but he soon redeemed himself a minute later. He assisted Luis Suarez on the right, who took one touch and rifled the ball straight into the back of the net.
Just as Barcelona asserted their dominance, Javier Mascherano's services were brought back into action as he made a crucial block to ensure Escudero's dangerous shot failed to reach its destination.
In a match wide open, Barcelona were keen to risk their lead in order to wrap it up themselves. Steven N'Zonzi's header went tantalizingly close before Sergio Rico was on hand to brilliantly deny Suarez of netting his second.
Sevilla left no stones unturned in the dying moments - throwing it all at the visitors - however were fortunate not to concede late as Neymar found himself in acres of space but before shooting he was closed down well by Sergio Rico.
