Kenneth Omeruo waited till deep into stoppage time to deliver the winning goal for CD Leganes to deny compatriot Sadiq Umar and his club UD Almeria leadership of the Spanish Segunda Division tonight.
Sadiq scored his 12th goal in the league courtesy of a sweet finish after just eight minutes of action in Madrid.
However, the home team drew level minutes after the restart, before Omeruo made the difference in time added on.
Leganes thus remain in fourth place on 46 points, while Almeria have 49 points and are third.
Mallorca lead the championship with 51 points.
