Mario Hermoso scored two own goals as Leganes beat Espanyol 3-2 on Sunday afternoon.
Hermoso diverted the ball into his team’s net to give Leganés an early lead, but Marc Navarro levelled the scores early in the second half.
Miguel Ángel Guerrero’s header and another Hermoso own goal put Leganés in front again, and they survived Hermoso’s bundled finish to hold on for three points.
Boosted by their famous victory away to Real Madrid in the Copa del Rey, Leganés began the game with more authority over their fellow mid-table opponents.
The hosts took the lead when Hermoso deflected in full-back Joseba Zaldúa’s driven cross from the right, following midfielder Darko Brasanac’s attempt which struck the post.
The Catalan team survived further punishment before half time, as striker Guerrero failed to beat goalkeeper Diego López.
In the second period, Espanyol found an equaliser through defender Navarro who crashed in an effort at the near post after a direct and positive run at the Leganés backline.
Leganés took the advantage again with 25 minutes remaining when Guerrero directed an accurate header past a helpless López after José García’s delicious cross.
They went further in front when Hermoso sliced a clearance past his own goalkeeper following a dangerous delivery from Nordin Amrabat.
Hermoso was able to score at the right end, after Leganés stopper Ivan Cuellar’s punched save cannoned fortunately off the centre-back following a free kick, but Espanyol couldn’t grab a crucial late goal in the final five minutes.
The victory leaves Leganés in tenth position, while Espanyol lie in 14th following their loss, but remain comfortably clear of the relegation zone for now.
Espanyol are next in action at home against local rivals Barcelona, who were their conquerors in the Copa del Rey quarter-finals.
For Leganés, they travel a short distance to face Madrid neighbours Getafe.
