Granada moved within touching distance of Primera Division survival with a hard-fought 2-1 win over Espanyol thanks to two goals from Odion Ighalo.
The Nigerian produced a great turn and finish to slot home Franco Jara's cross just before the half-hour and Ighalo was on hand again six minutes later to head home a much easier finish from David Cortes' cross.
Espanyol have not recovered from a two-goal half-time deficit for nine years but they did give themselves hope when Didac Vila's drive from 30 yards flew in off a post.
Coutinho, Alvaro Vasquez and Rui Fonte all passed up clear opportunities to bring the visitors level as they slipped to their third consecutive defeat.
Granada will be mathematically safe should Sporting Gijon and Real Zaragoza fail to win against Villarreal and Levante respectively over the next 24 hours, and they set about their task with some purpose right from the off.
Ighalo had an effort trapped at his near post by Christian Alvarez inside three minutes before the Espanyol goalkeeper made a spectacular stop to parry Carlos Martins' volley eight minutes later.
Julio Cesar turned Ndri Romaric's fierce drive from distance over the bar on 25 minutes, but moments later the hosts were in front as Ighalo controlled Jara's cross and spun away from the defence brilliantly before firing past Alvarez.
Six minutes later Ighalo doubled his tally as Cortes' dipping cross from the right fell perfectly for the striker to head home his sixth goal of the season.
Mauricio Pochettino's words at half-time seemed to have an effect on the Catalans as they were much improved after the break and got a goal back on 54 minutes when Didac's speculative effort left Cesar with no chance.
Substitute Coutinho poked just wide when one-on-one with Cesar moments after coming on and the Brazilian keeper had to alert again minutes later to block Alvaro's shot after he latched onto Borja Gomez's slack backpass.
Rui Fonte should also have done better when he headed over Didac's cross but Alvarez was also forced into a wonderful save five minutes later to turn away Inigo Lopez's side-footed effort.
Cesar made one final save from another Rui Fonte header 10 minutes from full-time but Granada comfortably saw out the final few minutes.
