Barcelona will be wearing special rolling stones shirts when they face off against Real Madrid on Saturday.
The La Liga giants will be hoping to leapfrog their rivals in the table, with just a point separating the two sides.
Barcelona won the title last term, with Real struggling at times under Carlo Ancelotti - having won the Champions League the previous season.
And it promises to be a blockbuster clash between the two Spanish giants.

Barcelona are set to wear Rolling Stones 'hot lips' shirts for the showdown.
And that's because they recently announced the band as their latest musical collaboration.
The Stones' famous lips symbol will replace the Spotify branding that normally goes on their famous red and blue shirts.
The match will take place at the Estadi Lluis Companys, their temporary home while the Nou Camp is being renovated.
Barcelona's women's team will also wear the Rolling Stones logo when they go up against Sevilla in November 5, too.
Their deal with the band coincides with the release of the Stones' 26th album, named 'Hackney Diamonds'.
It is their first album since the death of drummer Charlie Watts, who passed away in 2021.
The Rolling Stones also have a long-standing commercial agreement with Ligue 1 giants Paris Saint-Germain.
And it'll be interesting to see if the presence of their famous emblem curses Barcelona - or fuels them onto victory.
Barcelona boss Xavi has faced the media ahead of the crunch showdown with the club's biggest rivals.
And he's confirmed Robert Lewandowski, Frenkie de Jong, Pedri and Jules Kounde are now back in training as the match looms.
"I was surprised [that they were all able to train]," he said.
"The sensations during the session were very good.
"We will see how they feel later and will name the squad on Saturday. It's fantastic to have them all back training.
"Players we had ruled out want to play. Everyone is making a huge effort because they want to be involved in the Clasico, but we won't start anyone who is not 100 per cent."
Xavi also confirmed Pedri was no longer suffering with injury - hinting the Spain international will feature.
"There is no problem with Pedri," Xavi revealed.
"We had deadlines in place and he's more or less ticked them all off during his rehabilitation."
And, on the importance of the fixture, he added: "This game means a lot.
"It's the Clasico and every player in the world wants to play in it.
