Zinedine Zidane is reportedly under pressure to keep his job as Real Madrid manager.
While Los Blancos have recorded two points per game in La Liga this season, the defending champions sit 10 points adrift of city rivals Atletico Madrid.
Zidane has also witnessed his inconsistent side bow out of the Copa del Rey to minnows Alcoyano, leaving club officials to contemplate the Frenchman's long-term future.
Providing that Real do not win Spain's top flight against the odds, AS claims that Zidane must win the Champions League in order to keep his job.
Real have been provided with a last-16 tie against Atalanta BC, with the first leg taking place in Italy on February 24.
An early exit from that competition may prompt the powers-that-be at the Bernabeu to make a change in the dugout before the end of the campaign.
