Barcelona boss Luis Enrique has refused to comment on reports of divides in the Real Madrid camp.
Los Blancos, who still top La Liga, were beaten 4-0 at Atletico Madrid at the weekend.
Following the heavy loss, a number of Carlo Ancelotti's squad were pictured at Cristiano Ronaldo's birthday gathering, which has reportedly caused rifts in the squad.
"It's up to them to worry about their concerns and we'll worry about our own," Inside Spanish Football quotes Enrique as saying.
Barca will face Real Madrid in the league on March 22.
