Alberto Contador has announced he will retire from professional cycling following the Vuelta a Espana next month.

The 34-year-old Spaniard, one of only six riders to have won the Tour de France, Vuelta and Giro d'Italia in their careers, confirmed the news in a video message on Instagram.

He said: "Hi all. I'm doing this video to inform you about two things. One is that I will be participating in the next Vuelta a Espana, from August 19, and the second is that will be my last race as a professional cyclist.

"I'm saying this happy, I'm not saying it with sadness. It's a decision I've thought about very well and I don't think there is a better farewell than in my home race, in my country.

"I'm sure they will be three fantastic weeks, enjoying all of your affection, and I can't wait. Greetings and see you on the road from August 19th."
