Vasyl Lomachenko bids to take another step towards greatness tonight when he takes on Luke Campbell.
The Ukrainian already holds three lightweight world titles and can add another with victory over the Brit.
That would leave him just one short in the 135lb division - not bad for a man with 14 professional fights.
Of course, Lomachenko had a glittering amateur career and he comes up against another Olympic champion in Campbell.
The Hull man failed in his first attempt at winning a world title when he was beaten by Jorge Linares two years ago.
But he has since joined up with new trainer Shane McGuigan and is confident of pulling off a seismic shock.

"The fight is won tomorrow in the ring. I don't know how he has been this week, I've just concentrated on myself and we've been very relaxed and confident.
"This is where I want to be and the stage I love. You'll see the best of me - it's going to be explosive."
