Luis Enrique’s Barcelona were handed their second defeat of the season thanks to a spirited display by Sevilla who saw off the La Liga champions 2-1 at the Ramón Sánchez Pizjuán stadium on Saturday.
Krohn-Dehli broke the deadlock to put the home side in front seven minutes after the interval before Iborra made it 2-0 for the Andalucians six minutes later.
Barcelona scored from the spot after a Sevilla defender handled the ball inside the penalty with Neymar stepping up to put the ball past Sergio Rico for 2-1.
There was no shortage of action in the first half at Sanchez Pizjuan but there was nothing to separate both sides after the opening 45 minutes.
Claudio Bravo had been missing for the past month with a calf injury, but he was fit enough to reclaim his place in goal for Barcelona at the expense of Marc-Andre ter Stegen’s.
Elsewhere, Jordi Alba, Sergi Roberto and Munir El Haddadi all made the starting XI with Dani Alves, Andres Iniesta and Sandro Ramirez dropping to the substitutes’ bench.
Sevilla on the other hand fielded a defensive-looking XI with Vicente Iborra and Vitolo preferred to the more stylish and technical Jose Antonio Reyes and Yevhen Konoplyanka.
Sevilla flew out the traps for the restart as they took the lead just after seven minutes as Gameiro left Mathieu in his wake with electric pace down the right before squaring the ball to Michael Krohn-Dehli at the far post to finish off.
shortly before the hour mark, Dane superbly exploited Barcelona’s faltering offside trap with a perfectly-clipped ball for Iborra to guide past Bravo for 2-0.
Barcelona eventually began to probe but Rico who saved three Neymar attempts from close range consecutively was still not to be beaten.
Rico’s goal would soon be breached, however, as Benoit Tremoulinas was perceived to have blocked Sandro Ramirez’s shot with his hand in the box. Up stepped Neymar, who pulled one back for his side from the penalty spot.
