Real Madrid pair Raphael Varane and Fabio Coentrao were both present in the Spanish club's training session on Wednesday morning.
French international Varane has been out of action since the latter stages of last season after needing surgery to repair a torn meniscus.
Meanwhile, Coentrao, who came close to joining Manchester United on loan in January, has missed the last couple of weeks with a thigh injury that he picked up on international duty with Portugal.
Madrid began their Champions League campaign with a 6-1 win over Galatasaray on Tuesday evening.
