So Kambosos is trying in some undisclosed location and have a interview saying that it will be sweeter this time.
“It’s going to be sweeter this time, getting them back and becoming a two-time undisputed champion. This here is serious legacy, not only in Australian boxing but world boxing. This gives me goosebumps, that’s why I’m so motivated. The fire is burning. I can’t wait to get in there. I’ve been patient, but I am champing at the bit as well. This is legacy right here," Kambosos said to the Sydney Morning Herald.
