Karim Benzema and Dani Carvajal will most likely recover in time to play the crucial Clásico against FC Barcelona next November 21. Both of them have been on the sidelines for a while and Rafa Benítez has surely missed them during Real's recent games.
Benzema has no obvious replacement in this roster so Cristiano Ronaldo has been the one playing as the team's main striker when the French has been injured. Ronaldo's form could not be worse at the moment so playing alongside his French teammate could help him. Benzema is a crucial player in Real's offensive system and that's why Benítez will surely trust him as soon as he is ready to go.
Carvajal does have some competition for the starting spot, although Danilo's recent performances have not been great. Carvajal was playing very well until he got injured in the Madrid Derby and his return could also help Real Madrid.
