Barcelona have a crucial El Clasico clash against Real Madrid on Sunday night at the Camp Nou.

The results of this tie may go a long way in determining the outcome of the La Liga title race.

Barcelona have been rocked with accusations of refereeing corruption ahead of the tie, but Xavi has insisted that his team remain focused on beating Real Madrid.

“They will not destabilise us,” Xavi said in a news conference on Saturday.

“We are more stable than ever — and they have been trying [to destabilise us] now since Day 1.

“We are completely focused on winning on Sunday and making a big statement in the title race. … We are not thinking about anything else.

“It won’t be definitive if we win, but it would represent a real step forward. I am really up for it, it’s my first Clasico at Camp Nou [as coach] and I love these games.”

Barcelona are currently 9 points ahead of Real Madrid.
