Sevilla drew 0-0 at Real Sociedad on Sunday and let FC Barcelona escape at the helm of the Spanish football league, also failing to isolate in second place on Matchday 11.
With Daniel Carriço in the 'eleven' starter and without André Silva, injured, Sevilla could not escape the 'null' and was four points behind the Catalans, provisionally in second place, with Atletico Madrid and Alavés.
On Monday, in the game that closes the round, Espanyol can overcome these three clubs if they win in the reception to Athletic Bilbao.
Alavés were really the big losers of the day, after falling 2-1 at the Eibar ground in a meeting in which it was winning, eventually allowing the turnaround already in time of discounts.
Diop, at 90 + 1 minutes, gave the triumph to the home team, which featured Paulo Oliveira in the center of defense.
For his part, Reuben Semedo started the tie (1-1) at Huesca with Getafe, who also had Antunes full time. Villarreal and Levante also tied for one.
