Cristiano Ronaldo: I Can't Promise Another 20 Years of Football

Juventus and Portugal star Cristiano Ronaldo pointed out on Saturday to his retirement, during his celebration with his 36th birthday.

Ronaldo celebrated the occasion by posting a picture of himself and his family sharing a birthday cake.

"36 years old, unbelievable!" he wrote on Instagram.

"It feels like it all started yesterday, but this journey is already full of adventures and stories to remember by. My first ball, my first team, my first goal... Time flies!

"From Madeira to Lisbon, from Lisbon to Manchester, from Manchester to Madrid, from Madrid to Turin, but above all, from the bottom of my heart to the world... I've given everything I could, I never held back and I've always tried to deliver the best possible version of me.

"In return, you gave me your love and admiration, your presence and your unconditional support. And for that, I'll never be able to thank you enough. I couldn't have done without you.

"As I celebrate my 36th birthday and my 20th year as a professional footballer, I'm sorry that I can't promise you 20 more years of this. But what I can promise you is that, as long as I keep going, you'll never receive less than 100 percent from me!

"Thank you once again for all your support and for your kind messages and initiatives during this day. It means a lot to me and you all have a special place in my heart."
