Real Madrid star, Cristiano Ronaldo insists on full fitness ahead of the UEFA Champions League final.

The Portuguese star player played down fears over his fitness despite being forced to leave Real's training session on Tuesday, which was part of an open media day, after competing for a ball with reserve goalkeeper Kiko Casilla and collapsing to the floor.

The three-time Ballon d'Or winner kept on saying it was a minor scare even though several members of Real Madrid's medical staff helped to pick the star forward up off the floor, and the Portugal international was able to hobble off the pitch unassisted. Ronaldo left the session with training still in progress, and was seen to throw a water bottle away in anger as he headed for the changing rooms.

After the training session, Ronaldo insisted his limp was nothing more than the result of a dead leg. He said "I am fine. I had a little problem in training, a dead leg as they say here, but tomorrow [Wednesday] or the next day I will be fine. It was a minor scare, a knock."

Ronaldo came off at half-time of Real Madrid's final game of the La Liga season at Deportivo La Coruna 10 days ago having scored twice in the first half to take his tally for the season to 51.

He then sat out a practice match on Saturday ahead of this weekend's showdown with city rivals Atletico at the San Siro in Milan. Prior to this latest injury scare, coach Zinedine Zidane said Ronaldo would be fit for the Champions League final, despite a persistent thigh problem. Real Madrid are firm favourites to claim their 11th Champion's league trophy according to the odds at bookmaker StanJames.

Ronaldo mentioned the reason for his problems when he said "I believe I'm in better shape. I've had a slight problem but it's normal as I have been the most used player in the team. I think this is the season where I have played the most minutes. Besides the problem of today's training session, I believe I'm at my best level."
