Ronaldo back in training ahead of Champions League final

Madrid- Real Madrid star Cristiano Ronaldo alleviated concerns over his fitness ahead of Saturday's Champions League final against Atletico Madrid as the three-time World Player of the Year returned to training on Wednesday.

Ronaldo limped off towards the end of training on Tuesday after suffering a knock on a persistent left thigh problem.

Real's all-time record scorer missed three games last month due to injury and was also left out a practice match on Saturday by coach Zinedine Zidane as a precaution.

Ronaldo is aiming to break his own record of 17 Champions League goals in a season in Milan having already netted 16 in the competition so far this campaign.

The Portuguese set his record mark with a goal from the penalty spot as Real beat Atletico 4-1 after extra-time in Lisbon two years ago in the only other final between two sides from the same city.
