lionel Messi set up luis Suarez's 90th-minute equaliser to help Barcelona salvage a 1-1 draw at Real Betis Sunday, but the result could leave the Catalan club even further adrift of the Spanish league lead.
Real Madrid, which has a game in hand, can open a four-point gap if it beats Real Sociedad at the Santiago Bernabeu Stadium later on Sunday.
Sevilla can move three points in front of Barcelona if it wins at Espanyol.
"This result wasn't in our plans, but we have the entire second half of the league still to play and we have to keep putting pressure on the teams ahead of us," Barcelona coach luis Enrique said. "The most consistent team at the end will win. It feels like we won a point today."
Barcelona was outplayed during most of the match, and the hosts opened the scoring in the 73rd minute after goalkeeper Marc-Andre ter Stegen failed to get to a corner kick cross. Betis forward Alex Alegria got to the loose ball and easily scored from in front of the net.
Betis had a few good chances to put the game away, the best one came when striker Ruben Castro broke free toward the goal in the 80th but couldn't beat the goalkeeper from close range.
"We had more chances but we couldn't capitalize on them," Alegria said. "It's never a bad result to draw against Barcelona, but after the game that we played today, it's a shame that we didn't get the victory."
Barcelona also appealed for a penalty after an apparent foul on Neymar. The defending champion finally equalized after Messi stole the ball outside the box and immediately sent a perfect through ball to Suarez, who found the low right corner as the goalkeeper charged from the net.
