Joao Felix opened the scoring for Barça at the conclusion of a great collective movement (38th, 1-0) taking advantage of an assist from Lewandowski.
Deprived of their prodigies Gavi, Pedri, Valde, in addition to De Joug and others, the Blaugrana relied once again on Lewandowski who was in all the shots by scoring the second goal of this shock, two minutes after the start of the 2nd half.
Fermin Lopez Marin widened the gap with a 3rd goal (65th), thanks again to the Polish striker who did it again by placing a perfect cross on the head of young Fermin to consolidate the Catalan victory.
Undefeated for ten games in all competitions, Barça (2nd, 64 points) overtakes its Catalan neighbor Girona (3rd, 62 points) and remains eight lengths behind Real, solid leader.
