Over the years, Foreman revised his opinions on Ali and on The Rumble in the Jungle, on several accounts. In 2012, The Daily Telegraph reported Foreman's declaration: "We fought in 1974, that was a long time ago. After 1981, we became the best of friends. By 1984, we loved each other. I am not closer to anyone else in this life than I am to Muhammad Ali."Foreman also stated: "Then, in 1981, a reporter came to my ranch and asked me: 'What happened in Africa, George?' I had to look him in the eye and say, 'I lost. He beat me.' Before that I had nothing but revenge and hate on my mind, but from then on it was clear. I'll never be able to win that match, so I had to let it go.
