Real Madrid winger Cristiano Ronaldo could be sidelined for another month with his troublesome ankle injury.
The Portugal international, who moved to Real in the summer for a world record £80million fee from Manchester United, is to consult his former specialist, Professor Niek van Dyjk, who treated the same ankle last year.
Ronaldo picked up the injury to his right ankle in September and aggravated it playing for Portugal almost four weeks ago.
"He cannot train and must continue treatment and relief work until another examination is made," read a statement from Real.
The 24-year-old scored nine goals in seven matches for Real with Manuel Pellegrini's side winning all seven of those games.
In the seven games that Ronaldo has missed, Real have won just twice, and failed to beat AC Milan in the Champions League both home and away in the last fortnight.
It was initially hoped that Ronaldo would only be sidelined for between three and four weeks.
