Marc-Andre Ter Stegen - 5.5/10
The German keeper should have done better with Asensio's admittedly great strike from range, but stood rooted to the spot as it dipped under the bar. He couldn't do much for the second goal, while denying Benzema with a great save early in the second half.
Javier Mascherano - 5.5/10
The Argentine looked uncomfortable with his role in the 3-man defence, and had to constantly cover for Sergi Roberto. A couple of well-placed chipped passes going forward were offset by Mascherano losing possession repeatedly, including one which nearly resulted in a goal for Vazquez.
Gerard Pique - 5/10
The Spanish captain looked incredibly rusty, and kept getting dragged out of position by Benzema, with Pique left unsure of how to occupy defensive spaces with 3 at the back. Looking so inferior to Madrid and the 'se queda' chants must have hurt him more than the thigh injury with which he came off soon into the second half.
Samuel Umtiti 4/10
The Frenchman had a nightmare at the back, and was at fault for both goals. A poor clearance gifted Asensio the space to wreak havoc, while he allowed Benzema to ghost past him for the second. He did block a couple of shots in the first half, but his normally assured passing was non-existent.
Sergi Roberto - 5/10
Despite the presence of Marcelo, Roberto was caught upfield multiple times in the first half. He struggled to deal with Asensio and ought to have been booked for tugging him back. As soon as Nelson Semedo came on, Roberto looked much improved, and came close to scoring with a couple of well timed runs into the box in the second half.
Jordi Alba - 4.5/10
The Spaniard looks a shadow of the player he was just two seasons ago. He was unable to deal with the twin threats of Carvajal and Vazquez, with predictable results. Alba was found on the overlap in the second half more often, but failed to put in a telling cross on more than one occasion.
Sergio Busquets - 3.5/10
Unrecognizable from the player who was the best in the world in his position - Busquets was harassed into losing position multiple times and looked lost in the blur of Madrid's midfield rotational three. Barcelona's defensive pivot also lost the ball in midfield that led to the second goal, and things did not improve - he was the Blaugrana's worst player on the pitch. Paulinho may not seem such a bad buy right now.
Ivan Rakitic - 5/10
The Croatian was harassed into losing possession as well, but he did try to create things going forward, with a much-improved performance in the second half. However, he still looks unable to replace the energy he displayed in the 2014/15 season, and Barca need another body in midfield of a similar ilk.
Andre Gomes - 4.5/10
The much-maligned Portuguese midfielder looked bereft of ideas with the ball at his feet, thus stunting any transitions into attack. He did make a couple of late runs into the box, where a better pass may have resulted in a goal, but overall, Gomes' contribution was minimal at best.
Luis Suarez - 5.5/10
The Barcelona forward had one of those days - he should have gotten on the scoresheet in the second half with a diving header but watched in agony as it hit the post. Suarez was full of running and did look like the only Barcelona player who believed in a comeback while the rest of his teammates had already given up the ghost.
Lionel Messi - 5/10
It's not often that Messi gets such a low rating, even when Barcelona are disappointing. The Argentine wizard tried to do too much, often attempting to force his way through midfield when there was a simple pass to Suarez available. He did hit the crossbar when it looked incredibly difficult to score.
Nelson Semedo - 5.5/10
The Portuguese fullback made his Barcelona debut in difficult circumstances but immediately looked an improvement over Ernesto Valverde's current options. Semedo was eager to get forward at every opportunity, although still needs to come to terms with his teammates' wavelength.
Gerard Deulofeu - 4/10
The Barca product was brought back to make up the numbers, and it seems that will also be his contribution on the pitch. He held on to the ball for way too long in promising positions, and looks alien in Barcelona's frontline.
Luca Digne - 4.5/10
The Frenchman replaced Jordi Alba, but did not look much of an improvement, barely offering anything going forward.
