Barcelona (AFP) - Jordi Alba scored an extraordinary volley and Dani Alves was sent off as Barcelona delivered a major boost to their hopes of finishing in La Liga's top four on Sunday by winning a six-goal thriller against Atletico Madrid.
A rampant Barca scored four goals in 40 minutes at Camp Nou before surviving a late fightback from Atletico after Luis Suarez headed in against his former club and Alves saw red with 20 minutes left.
A statement victory returns Xavi Hernandez's side into the top four for the first time since September, with Atletico now two points behind in fifth.
"The team, the fans and the club in general needed a win like this," said Xavi."It could be a turning point, we can't hold back now."
Atletico coach Diego Simeone said: "If we took advantage of our opportunities everyone would be saying how good our counter-attack was.Their effectiveness has prevailed today."
Atletico took an early lead through Yannick Carrasco but Barcelona came storming back, Alba equalising with surely one of the goals of the season before Gavi, Ronald Araujo and Alves all struck to leave Atletico facing an annihilation.
Instead, Suarez headed in and Alves was sent off as tempers flared.But Barcelona held on, with Pierre-Emerick Aubameyang, signed from Arsenal, coming on off the bench to make his debut in the second half.
With Barcelona in containment mode, Aubameyang's influence was limited and it was another January signing, Adama Traore, who made the biggest impact with an electric first-half performance.
Barca were ninth in the league, six points behind Atletico in fourth, when Xavi was appointed coach.
Now, they are in the driving seat to seal qualification for the Champions League, which would be so crucial to their financial recovery.
Traore, a La Masia graduate, and fellow new signing Ferran Torres both started but Aubameyang was only deemed fit enough for the bench, along with Ousmane Dembele, who Xavi welcomed back into the fold despite threats of exile from the club.
Dembele is yet to extend his deal, which expires in the summer, and the Frenchman was whistled before kick-off and not brought on in the second half.
"I was going to bring him on but the situation changed after the red card," Xavi said.
Traore in full flow
Atletico were ahead on eight minutes but the rest of the first half belonged to Barca.
Traore was at the heart of it, making the game his own for a whirlwind half an hour.
He pressed and harried and terrorised Atletico, until Simeone even had to bring Carrasco over from the right for cover.
Traore was involved in Alba's equaliser too, his cross poked out to Alves, who floated the ball to the opposite side, where Alba had time to adjust his feet and let fly with a stunning volley.The ball flew over Jan Oblak and into the far corner.
Barcelona were on top and Traore in full flow.He stopped Mario Hermoso, then surged past him, lifting a cross off the line and into the area where Gavi headed in a second.
Pedri should have made it three but fired over and as Atletico hoped for half-time, Barcelona struck again, Alves' chip headed onto the crossbar and the ball bouncing up for Araujo to smash in.
Four minutes after the restart, Barca made it four, Gavi's cut-back finding Alves, who arrowed a finish into the corner.Alves milked the celebration, posing with his arms outstretched after his first Barca league goal since 2013.
But the party atmosphere was popped when Suarez reduced the gap to two by heading in from close range.
Aubameyang briefly broke the tension by coming on to rapturous applause for Traore but Alves was then sent off after scraping his studs down the back of Carrasco's leg.
Atletico had 20 minutes to score two and the game almost boiled over when Xavi's assistant Oscar Hernandez was shown a red card for his protests and Xavi saw yellow.
A third for Atletico and Barcelona might have caved but it never came.
