Brazil legend Ronaldinho releases his first solo single

With his professional football career now seemingly done and dusted, Ronaldinho has freed himself up to fully pursue his other main passion in life: his music.

Indeed, having appeared as a guest on several records in the past, the 37-year-old has proudly unveiled his very first self-penned ditty -- a lilting samba ballad called "Sozinho" which translates as "Alone".

The lyrics appear to be of a personal nature, with Ronaldinho crooning: "Me, now alone. I do not feel weaker or stronger but who knows the fate? Comfort me in this battle.

"Alone for the first time. Alone, the mind goes beyond the beyond. Alone, but with strength and faith to continue."
