Cristiano Ronaldo has expressed his delight at signing a new contract with Real Madrid.

Los Blancos on Sunday announced Ronaldo, 31, has extended his stay at the European champions until 2021.

"I would like to thank the Real Madrid president, the club, my team-mates, those who have helped me reach this stage," said the Portugal captain, who joined Real in 2009 in a £80 million transfer from Manchester United.

"It's a very important day. I have said many times that I carry this club in my heart, it's part of me.

"In a very special moment of time in my life, I'm going to be here for another five years. It's not going to be my last contract, let it be known, but it's very special.

"My thoughts are I want to continue being the best. I want to wear this shirt with pride and I'm sure I'm going to continue contributing the same over the next five years as I have been, scoring goals and winning titles.

"I have to wait and see [about the date of my retirement]. Who knows what the future holds. Of course, I would like to end my career at this club. This is my penultimate contract. I want to be here for many years to come. I'm overjoyed."
