Cristiano: "The injury is fine, and I'll come back stronger"

The Real Madrid striker, who played a key part in leading his country to a maiden major title, limped off in tears with a knee injury in the first half of the final against hosts France earlier this month.

Could miss first three games of season

The 31-year-old has a sprained ligament in his left knee, and he is unlikely to return to action before Real's third game of the domestic La Liga season.

"Hi everyone! I just wanted to thank all my fans," Ronaldo said in a video on his Instagram account.

"I wanted to tell them that all is well and that I will come back much stronger. Thank you, long live Portugal!"

After suffering the initial injury, the three-time Ballon D'Or winner tried to play on but had to be replaced in the 25th minute, before striker Eder grabbed the only goal of the game in extra time.
