"The day has come where we say goodbye, today ends a six-year spell with Roma. I arrived here as a kid full of dreams; a first season that was so-so but saw me make my debut for Brazil, a second where I thought we would realize the biggest dream, the title, only to face an opponent (Juventus) difficult to stop.

"Nevertheless, I went on holiday that summer with the thought that the third season would be the one - I felt in the form of my life and was sure that we would win it all. Unfortunately it was then that I was faced with a challenge I never even dreamed of. Only myself and my family just how tough and how long that battle was, the proudest victory of my career. God, yes, Him, he exists - because without him I would not have made him and I thank him every day.

"Over time I lost my place at Roma, but I will forever be grateful to everyone there. I did not manage to win a trophy with you but I hope I gave you an important lesson - to never give up, never ever give up! It does not matter how often or how badly you get beaten, how difficult it seems, never give up! I still have not given up and will never give up!

"I salute you all, I will follow a new path now but I will always support Roma along the way! The kid full of dreams continues his adventure! God will guide the way! Forza Roma sempre!"
