AC Milan coach Carlo Ancelotti insists there's no concerns over Ronaldo's fitness.

"Ronnie will be in the starting line-up at Siena on Saturday September 15. I think there is a lot of confusion over what's happening, because this is simply an injury that he needs to recover from," said Ancelotti.

"This break will be very useful to give him the time to work and get back to his best. These things can stretch on because when it comes to a muscular injury, one has to proceed with caution and be 100 per cent sure."
