Olmo gave Barca the lead in the first half and then netted late on to seal their victory in the second match back at their partially rebuilt Camp Nou home. Atletico Madrid rose to third with a 2-0 win over Real Oviedo, thanks to Alexander Sorloth's double. Meanwhile, Alberto Moleiro helped Villarreal rise to joint-second with a stoppage time winner in a 3-2 victory at Real Sociedad....
