Real Madrid president Florentino Perez is ready to sack coach Julen Lopetegui.

Marca says Lopetegui's fate has been decided by Perez and the Real Madrid board, with the coach set to be sacked after the next defeat.

Only a phenomenal turnaround in form, something akin to five consecutive victories, would see him save his long-term future.

He is only going to be in the dugout against Viktoria Plzen on Tuesday night because there has been so little time to make a switch.

There is no margin for error remaining and he'll be sacked after the next defeat, or even if the team turns in a very poor performance.

Every game is like match point for him now, and he must win and win well against the Czech side on Tuesday to find himself coaching at Barcelona on Sunday.
