Gareth Bale could miss Real Madrid's La Liga clash away to Rayo Vallecano on Wednesday due to a foot injury.
"We have had problems with Bale, who has a knock on his left foot which we will evaluate," Real coach Carlo Ancelotti said in his pre-match press conference on Tuesday.
The Welshman scored the opener in Real's 9-1 demolition of Granada on Sunday, but Ancelotti won't be short of options should Bale miss out with all four of Isco, James Rodriguez, Luka Modric and Toni Kroos available for the first time in five months.
Rodriguez made his return after two months out with a foot injury in the place of the suspended Isco at the weekend, but Ancelotti claimed they wouldn't be vying for just the one place in the side and that his preferred front three of Bale, Karim Benzema and Cristiano Ronaldo could be rotated in the coming weeks.
"We have a game every three days until the beginning of May and the rotations will be necessary," he added.
"There isn't a debate between James and Isco, it is between the whole squad which is a good thing. We have almost the whole squad in optimal condition.
"James is doing very well in his first year, but Isco is also a great player who has had some fantastic games. I am lucky to have them both. It is a good problem to have."
Pepe remains the only injury absentee as Madrid continue their pursuit of La Liga leaders Barcelona.
The European champions could be as much as seven points off the top by the time they kick-off at Vallecas, though, with the Catalans in action at home to Almeria earlier on Wednesday.
