"It's possible," he said. "I'm not going to obsess about it. Of course, goals are great and I identify myself with scoring. But the most important thing is winning titles."

Despite his incredible achievements in a Madrid shirt, the length of the contract has been questioned with Ronaldo struggling to match his form of old so far this season.

"To score or not score is not so important as you think," said Perez.

"It is a little bit of a blip, but that is part of life. I know that in two, three weeks or a month, Cristiano will be there as always."

Ronaldo has again been shortlisted for the world player of the year award.

"This is the best moment of my life," he said.

"To win the Champions League, then win Euro 2016 and sign a new contract with this club, I can't ask for more. It's truly special."

Ronaldo has failed to score in five successive games at Bernabeu stadium, but he has mustered seven goals in 12 appearances this season and he thanked Perez for his unwavering support.

"Football has no memory, but you (Perez) have a memory and that makes me happy," he said.

"During a career, there are good and bad times but I always want to learn and football teaches you a lot."

Perez is predicting many more great moments from Ronaldo, whose previous contract paid him about $435,000, a week according to media reports.

"You never give up, you always want more and for that reason you remain in this club," Perez told Ronaldo.

"We know there will be much more from you because you never get tired of winning."
