As reported by 'Mundo Deportivo', Benzema began to feel pain in his foot during the first part of training on Tuesday, as a result of a knock. Although he was able to complete the session, in some of the sections of training he was seen limping.
The forward collided with a teammate in a mini-game during a light warm-up session. He then received attention from the medical staff, and continued training, but there is concern in the Madrid camp.
With just four days remaining before the final, any problem could relegate Benzema to the bench in Kiev, where he could be replaced by Gareth Bale, who has finished the season in good form.
The clock is ticking for Karim, however it remains to be seen how serious the problem is, and the fact that the Frenchman was able to finish the session is a positive sign for the club.
