As well as being a champion boxer and a master orator, Muhammad Ali was a humanitarian that regularly spoke up for people in need.
He was a famous advocate for civil rights in America, as well as objecting to the Vietnam War, but even away from topics that impacted him personally, Ali was always willing to lend his voice to a worthy cause.
The American, who sadly passed away last night, had that in common with U2 frontman Bono, whose philanthropic work with charities is well documented.
It seems that the duo had struck up a friendship in the legend's later years, as Ali wished the Dubliner a happy birthday with one of his final tweets.
