Real Madrid beat Paris Saint-Germain 3-1 in the first leg of their Champions League round of 16 clash at the Santiago Bernabeu but may be without a couple of key players for the return fixture.

Both Marcelo and Luka Modric are injury doubts for the second leg in Paris on March 6.

“[Modric] has pain in his leg,” Zinedine Zidane said.

“The situation is that he isn’t training and thinking only of recovering quickly.

“I don’t think it is much, but as always I have faith in all the people who work here; the physios and the doctors, so that it is small and he returns soon.”

The club released a statement updating the status of the midfielder which revealed that he “has been diagnosed with a a muscle injury in the biceps femoris of the right leg.”

Marcelo has also emerged as an injury doubt with the La Liga outfit releasing a medical report for the left-back as well.

“He has been diagnosed with a a muscle injury in the biceps femoris of the right leg. His recovery will continue to be assessed,” the statement read.
