Barcelona fullback Jordi Alba says its crucial they maintain their winning form.
The El Clasico against Real Madrid is looming next month.
“We are eight points [ahead] and it's very important,” the 23-year-old told AS. “Now we have to think about getting the three points against Sevilla.
“Hopefully we can keep the difference [between the clubs] up to the Clasico. But I would not rule out Atletico and Malaga [winning the league].
“We'll see if we can beat Madrid, it would be great to extend the distance. It was unthinkable that Madrid lost these games, so we are warned: it can happen to us.”
