Casadó red card and two goals for the home team turn a potentially wonderful result into a disappointing draw at Balaidos

Alfon Gonzalez and Hugo Alvarez were on target as Celta denied Barca the chance to move eight points clear at the summit, and Flick said his side could have few complaints

Celta were offered a lifeline eight minutes from time when Barcelona went down to 10 men after Marc Casado was shown a second yellow card. Just four minutes later the hosts had pulled one back, with Alfon Gonzalez capitalising on a Jules Kounde mistake at the back to poke an effort past Pena.
