Barcelona midfielder Sergio Busquets has claimed that the Catalan outfit need to "take a look in the mirror" following Sunday's 1-0 defeat at Real Sociedad.

Barca missed the chance to go top of La Liga after losing at the Anoeta, but Busquets is confident that the team will recover.

"We're a bit down not just because Real Madrid lost but because we wanted to start the year off with a win. Now we need to take a look in the mirror, and keep on moving forward," Busquets told the club's official television channel.

"It's tough to get going when you're losing from the outset. The other team sits back and it's difficult to get things going when they play like that.

"We don't lose much, but here it's always hard for us. Hopefully we can change that for next season."

Barca have lost at the Anoeta on four of their last five visits.
