Zinedine Zidane sends warning to Thibaut Courtois?

Real Madrid manager Zinedine Zidane has reportedly warned Thibaut Courtois regarding his poor form with Keylor Navas waiting in the wings to capitalise.

The Belgium international joined the Bernabeu giants from Chelsea in the summer under ex-boss Julen Lopetegui, but he has not been entirely impressive with a number of average performances through the season.

According to The Sun, Zidane was never in preference on signing Courtois during his previous stint with the club and he has now urged the Belgian to improve his showing or risk being dropped from the lineup.

Keylor Navas was a constant presence between the sticks for Los Blancos during Zidane's first stint and the Costa Rican could be reinstated between the sticks, should Courtois' average run of form continue.

Los Blancos have allowed 32 goals from the 27 league games this term, 24 of which have resulted when Courtois has featured in goal. He has kept just eight clean sheets in the process.
