Portugal's football legend Cristiano Ronaldo celebrates his 35th birthday today.
The veteran feels full of energy and insists that he could play football professionally for many more years.
"It will depend on my motivation, as I have never had any physical problems.
I take good care of myself and I really think I could compete until the age of 40. The most important thing is the psychological factor.
Of course, everything has its beginning and end, but for now I intend to continue collecting important trophies," Ronaldo said to "Marca."
