High-flying Girona reclaimed top spot in LaLiga after beating champions Barcelona 4-2 away on Sunday, condemning Xavi Hernandez's side to their second league defeat of the season.
Artem Dovbyk and Miguel Gutierrez both scored for Girona in the first half, either side of Robert Lewandowski's equaliser, before Girona's Valery Fernandez and Cristhian Stuani added two more goals after the break with Ilkay Gundogan netting another for Barca.
Girona, who remain unbeaten away from home in LaLiga this season, top the standings with 41 points from 16 games, having leapfrogged Real Madrid on 39 points after Carlo Ancelotti's side were held to a 1-1 draw by Real Betis on Saturday.
Barcelona, whose only previous defeat this season was to Real at the end of October, are fourth on 34 points, level with third-placed Atletico Madrid who have a game in hand.
"Girona have a lot of merit in what they are doing. They are in the lead, even more so today. They've got seven points more than us and that's well deserved," Xavi said.
"It was an even game. If Barca won, we would also say it's fair. I think we shot 31 times. Maybe the errors in defence have taken their toll on us."
Barcelona had 31 attempts in the game, 11 of them on target, but Girona keeper Paulo Gazzaniga pulled off a string of saves while at the other end they scored with four out of their seven shots on target.
Dovbyk put Girona in front in the 12th minute with a shot that bounced in off the bottom of the post for his eighth goal in his debut LaLiga season.
Lewandowski rediscovered his goal-scoring form and equalised for the hosts seven minutes later, heading home following a corner.
It was the Poland striker's first goal for Barca in nearly a month, following his brace against Alaves on Nov. 12.
Gutierrez restored Girona's lead before halftime, after the defender broke into the box and scored with an individual effort, and Fernandez made it 3-1 in the 80th minute with a low shot two minutes after coming off the bench.
Gundogan pulled another goal back for Barca before Girona's Stuani scored their fourth in stoppage time.
"This Girona side have a soul and believe they can hurt their opponents," coach Michel said.
"We knew that (Barca) were going to press hard but if we were able to make the first two passes, we would stand a chance."
Barcelona, who on Wednesday travel to Royal Antwerp in the Champions League, next visit mid-table Valencia in the league on Saturday. Girona host 12th placed Alaves on Dec. 18.
Atletico Madrid beat Almeria 2-1 on Sunday with first half goals from Alvaro Morata and Angel Correa, extending the bottom side's winless streak in LaLiga to 16 games.
The victory moved Atletico to third, level with Barcelona on 34 points and five points behind league leaders Real Madrid.
Antoine Griezmann had a goal ruled out for offside by VAR but he helped his side take the lead in the 17th minute when he won the ball high up the pitch before he found Morata, who dribbled into the box and rounded the goalkeeper to score.
Correa doubled the lead five minutes later when Marcos Llorente provided the cross from out wide for the Argentine forward to tap in from close range, another goal-scoring move that was orchestrated by Griezmann.
Almeria halved the deficit through Leo Baptistao who scored just after the hour-mark when the Brazilian forward pounced on a loose ball after Atletico goalkeeper Jan Oblak made a save.
Almeria, the only LaLiga side yet to win a game this season, had their chances in the second half to steal a point, but Oblak stood firm to deny the visitors as Diego Simeone's side returned to winning ways after losing to Barcelona last weekend
