Barcelona’s Jordi Alba own goal in the 2nd minute was enough to award Real Sociedad a 1-0 win over Barcelona in a La Liga match played at Sociedad’s home ground.
With Real Madrid suffering a 2-1 defeat away at Valencia, Barcelona had a perfect opportunity to go top of Liga BBVA, but that loss now meant that they will be still occupying the number two slot on the table, with just one point behind Real Madrid.
And BBC Sports Had this to report on that match
Coach Luis Enrique started with Lionel Messi, Neymar and Dani Alves on the bench following the festive break.
Messi, Neymar and Alves only returned to training last Friday after an extended break in South America during the league's Christmas shutdown.
Enrique took the gamble of starting without them for a fixture that has proved tricky for Barcelona in the past.
And they were unable to inspire a fightback as Moyes secured a memorable second win as Sociedad manager.
And so it proved again with their winless run at Anoeta now extended to six games.
