Real Madrid are preparing contingencies if Zinedine Zidane decides to leave the club this summer.
Massimiliano Allegri and Raul are considered the favorites, but not the only names on the shortlist.
Zidane has persistently refused to confirm that he'll see out his contract, which runs until 2022.
"There are moments when you have to stay, and others when you have to go," he hinted in a cryptic news conference on Saturday.
The radio station Onda Cero reported that Zidane told his players that he would not be carrying on as coach during a team talk ahead of their La Liga game with Sevilla last weekend.
Multiple players have said that it is not "very clear" what Zidane intends.
