Deportivo La Coruna moved to within three points of fourth-placed Valencia following a deserved 2-1 win at relegation-threatened Recreativo Huelva.
Joan Verdu gave Deportivo the lead after 17 minutes and although Adrian Colunga equalised for Recreativo just before half-time, Pablo Alvarez struck the winner four minutes into the second half to seal a fourth league win in five games for the Galicians, who now have a realistic chance of returning to the Champions League for the first time since 2004.
Deportivo lost to eventual champions Porto in the semi-finals that year, and that game marked the end of the much-lauded `SuperDepor' side, which had come up from the Segunda Division to win a Primera Liga title, two Spanish Cups, three Supercups and twice finish second in the league.
However, this Depor side has been quietly progressing under Miguel Angel Lotina, who is in his second season at Riazor.
And they went ahead with the first real chance of this game.
Following a tense opening quarter of an hour, Deportivo striker Rodolfo Bodipo saw his effort half-cleared on the edge of the box and the ball fell to Verdu, who beat Recre keeper Asier Riesgo with an exquisite lob.
It was a goal out of nothing and Recre will have felt unlucky to go behind.
The Andalusians had boosted their survival hopes last weekend with a 2-1 win at Osasuna.
Lucas Alcaraz's side had come from behind in that match and they would have to do the same now.
And it looked as if they might do just that as they pressed for a leveller in the build-up to half-time.
Javi Guerrero fired just wide five minutes before the break when he really should have scored.
But three minutes later, Recre were level.
Javi Fuego's neat pass found Colunga, who evaded Ze Castro and fired a clinical finish past Daniel Aranzubia to give the hosts a huge lift just before half-time.
Their joy was short-lived, though, because Deportivo retook the lead four minutes into the second half.
Filipe Luis charged into the Recre area and his clipped cross-cum-shot was forced home by Alvarez.
As so often this season, Recre's defence had gone to sleep.
And those lapses in concentration look set to send the Andalusians back to the second tier.
Deportivo will hardly care, though.
The Galicians were rather lucky to be ahead again, but they dominated the rest of the match.
Verdu hit the post later in the second half and also flashed a shot just wide from point-blank range.
Andres Guardado also missed a great chance to put the visitors two ahead five minutes from time when he found himself alone in the area, but the Mexico winger fired inexplicably wide and Deportivo were forced to suffer in the final minutes.
In fact, they needed a fine save from Daniel Aranzubia in the last minute to keep hold of the points.
The Basque keeper got down well to deny Guerrero and Depor held on for a deserved win.
Recre, meanwhile, missed a great chance to boost their survival hopes.
The Andalusians remain second from bottom, three points behind 17th-placed Osasuna.
