Real Madrid star Cristiano Ronaldo is convinced he can maintain his standards in the future.

Ronaldo isn't panicking over his current form slump.

"On a personal level, this is a fantastic time for me. I have a growing family and I am very happy with my life," he said. "On a professional level I have had two very good years in which I have won titles with my club and with my national team.

"I feel that I can keep going at the highest level for years to come."

Now 33, Ronaldo also told GQ: "I am ambitious, very ambitious. People should chase their dreams. I chased mine and I want to keep doing so, to improve and achieve even more goals. I believe I've had some memorable performances throughout my career but can't recall any in particular. I try to focus myself more on the present than on the past."
