Girona returned to the top of La Liga as Cristian Portu's first-half finish earned them a 1-0 win at Celta Vigo.
They leapfrogged Real Madrid, who defeated Las Palmas 2-1 on Saturday.
Portu finished emphatically past Vicente Guaita within the first 20 minutes to set the visitors on their way back to top spot.
Paulo Gazzaniga then denied the hosts on several occasions to secure victory for Girona, who sit one point above Real having played a game more.
Rafael Benitez's side enjoyed plenty of pressure but goalkeeper Gazzaniga - formerly of Tottenham and Southampton - stood firm for the visitors.
As Celta Vigo pushed hard for a leveller, the Argentinian acrobatically turned Jorgen Strand Larsen's header on to the crossbar before also denying Oscar Mingueza.
Girona held out for a clean sheet that ensured they returned to winning ways following their midweek Copa del Rey elimination at the hands of Mallorca.
