"It has been much longer than I ever dreamed, yet it feels so short that I'd live it all over again," he wrote in a social media post.
"With only three days left until the 'last dance', so many emotions, people, and memories come to my mind, and all I can do is sum them up in one huge THANK YOU.
"My heartfelt gratitude goes out to everyone who crossed my path, the greatest treasure of this profession. I carry a piece of each of you with me, and I won't forget that you've all helped me experience this genuine privilege of a career as a footballer.
"I'm proud and at peace with every moment I've experienced, the tough ones because they taught me, and the good ones because they've made me extraordinarily happy.
"I thank God for blessing me with a family who is responsible for every good thing that's happened to me; even a lifetime wouldn't be enough to repay them.
"See you soon. New projects are coming, and football runs through my veins... I couldn't understand life without it."
