The 28-year-old had rushed back to his home country on Friday because of a family illness but said that the problem was now resolved.

"I have to thank the club for giving me permission to leave because it was a difficult time for me," Ronaldo told the Real Madrid website.

"When I arrived back home luckily it turned out to be little more than a scare and now everything is sorted out. I was sorry to have missed an important game, but my team mates were in good form and we won the match (2-1).

"Everyone appeared a bit taken aback by the way I had to rush back, but it was a family matter and now there is no reason to worry."

Ronaldo missed team training on Tuesday morning, but later completed a fitness session on his own at the team's training ground in Las Rozas.

At the end of his personal training Ronaldo reaffirmed his total commitment for the club by saying coach Vanderley Luxemburgo could count on him anytime now.

"I have a week to train hard and be ready for the weekend," said the player, who, in referring to Barcelona, assured "we'll reach them at the top, and what we have to do now is to do our work: play well and win points."

The Brazilian superstar then made reference to Santiago Bernabeu Stadium whose grass was changed, indicating he saw this as a positive thing, and showed his happiness about the renewal of the contract of his mate, Santiago Solari, from Argentina.

"I hope Cesar, Celades, Figo renew their contracts. I want them all to do so, because we have great players and because we're good friends," he added.
