Real Madrid coach Zinedine Zidane insists they're in the title race.
Discussing Monday's opponents, Zidane had praise for Real Sociedad's style.
"They're a team who know how to play well," he said.
"We'll be at home and we want to keep collecting points.
"The season is long and there are still many matches left.
"We haven't won anything yet, so we have to continue.
"There are 42 points in play. Our focus is on tomorrow and only that. It's not on three weeks ahead.
"The title race is still open. You say that today it's a three-team title race, but tomorrow you might say another thing.
"In critical moments, this team prevails."
