Madrid, which has lost only once in the league this season, holds a 13-point advantage over second-placed Girona, while Barca dropped to third after this loss.

The victory saw Girona seal European football for the first time in its history.

A brace from substitute Portu helped LaLiga's surprise package Girona to humble its Catalan rival.

Andreas Christiansen scored in the third minute to give Barca the lead but Girona hit back a minute later, with LaLiga's top scorer Artem Dovbyk heading in the equaliser.

Robert Lewandowski put the visitors back ahead from the penalty spot just before the break.

However, in his first action after coming off the bench, Portu restored parity before Miguel Gutierrez scored from a rebound two minutes later to turn the match on its head.

That paved the way for a stunning volley from Portu in the 74th minute to secure the win.
