Granada went to the top of La Liga with success over Genuine Betis.
The Andalusian club, who were promoted from the second tier in the summertime, made the most of El Clasico being held off to go up from sixth to top with 20 points from 10 games.
Former Betis gamer Alvaro Vadillo scored the only goal with a close-range finish from Carlos Fernandez’s pass.
Granada are one point above Barcelona, Real Sociedad – who beat Celta Vigo 1-0 on Sunday – and Atletico Madrid.
Champions Barcelona could return to the top on Tuesday if they beat Genuine Valladolid, with a complete set of La Liga components throughout the week.
Granada have actually never won a major trophy in their 86- year history, going closest when they lost the 1958-59 Spanish Cup last to Barcelona. Their highest La Liga surface is sixth, on 2 events in the 1970 s.
