Background

[edit]

Alexandre, who is named after his grandfather, was born in São Vicente, São Paulo and raised in Santos, Sao Paulo. Growing up, Alexandre competed in football and was talented, going on to play professionally, but ultimately chose to focus on a career in Muay Thai.[3][4] Alexandre began training in Muay Thai at the age of 19.[citation needed]

Kickboxing career

[edit]

Alexandre began his professional kickboxing career in October 2004 in his native Brazil.

He was scheduled to have his rubber match with John Wayne Parr at Powerplay Promotions 22 in Melbourne, Australia on 8 November 2013.[8] However, he did not apply for his visa in time and was unable to enter the country and so he was replaced by New Zealand's Brad Riddell who Parr defeated by unanimous decision.[9]
