Cristiano Ronaldo is unlikely to play in Tuesday's Champions League match for Real Madrid against Borussia Dortmund after having a flare up in his left knee during Monday's training session.
Ronaldo took part in the warm-up but noticed problems with the joint when doing ball work.
In his press conference before the session, Carlo Ancelotti had said Ronaldo might be doubtful for the match: “It depends on the training session. If he’s not 100% he won’t play”.
