Barcelona striker Antoine Griezmann hailed their performance for Sunday's 6-1 win at Real Sociedad.

Griezmann opened the scoring against Real Sociedad as Barcelona won 6-1 on Sunday to keep the pressure on leaders Atletico Madrid.

Lionel Messi and Sergiño Dest both netted braces and Ousmane Dembele also scored as Barça kept within four points of Atletico at the top of La Liga.

"Sometimes we struggle to score the first goal but we were really fluid tonight and played really well," Griezmann told Movistar.

The French forward added that he didn't celebrate "out of respect for playing" for La Real earlier in his career as he celebrated turning 30 with another goal.

"Sometimes it's not your day in the final third, sometimes I miss, others times it's Ousmane or Martin... we work on that, to improve," he added.

"But here everyone scores goals. We have to be switched on mentally, those that aren't playing have to be attentive, they can make the difference, too. We're a group and that's the only way to achieve big things."

On the title race, Griezmann said Barça aren't focused on Atletico: "We have to look at ourselves and do all we can to be champions."
