Three goals from Luis Suarez have helped Barcelona overcome a stubborn Eibar side, who had taken the lead through Borja Baston, 3-1 this evening.
Baston had given Eibar a shock lead after following up Keko's parried shot, but Suarez cancelled it out 10 minutes later, heading in a cross after good work from Neymar and Dani Alves down the right.
Suarez's second came after Neymar danced into the box before unselfishly setting up the Uruguayan to finish emphatically in the bottom corner.
The striker then grabbed his third five minutes from time after coolly finishing in the far corner.
Neymar had a penalty shout turned down in the second half, before Ivan Rakitic and Sergio Busquets combined brilliantly to almost set up Suarez for his hat-trick.
Eibar threatened to equalise on the break and Barcelona found themselves down to 10 men after Javier Mascherano was given a red card after talking back to the referee.
Suarez then got his third goal two minutes after that to put the game beyond doubt.
With that win, Barcelona move up to second in La Liga, while Eibar sit in seventh.
