Meanwhile, the Italian has also insisted that Madrid boss Carlo Ancelotti needs to be given time to impress his system upon his new team.
"The players are getting used to understanding his system, Carlo needs time," Capello told El Primer Toque.
"However, I am certain that Real Madrid are the favourites for the Champions League. No team has players like that."
Madrid were beaten 1-0 by Atletico Madrid in La Liga at the weekend.
