Cristiano Ronaldo could resume training with club Real Madrid as early as Friday according to doctors, after he was tested Tuesday.

Ronaldo has missed a staggering nine games with his club due to an ankle injury picked up against Marseille late in September. He has been a key absence for both club and country, and the news on Tuesday that he could resume training as early as this Friday will serve as great news to fans.

Madrid supremo Emilio Butragueno was more cautious, "We need to take it day-by-day. The doctors will make the decisions."

He added, "I have the feeling Cristiano wants to be playing already and that enthusiasm could be harmful since it would be terrible if he re-injured himself."

The team are hopeful Cristiano will be back to first team action in time for the "El Clasico" encounter versus Barcelona later this month, if not sooner.
