Tim Tszyu says he's using Jeff Horn's upset win over boxing superstar Manny Pacquiao as inspiration to show he's ready to beat the Queenslander in their super welterweight fight.

The 10-round bout, for which Horn will pocket 60 percent of the money, has been confirmed for April 22 although the venue will not be decided until next month.


Former WBO welterweight champion Horn has told a joint media conference in Sydney he learned a lesson from his shock loss to Michael Zerafa last year and won't make the mistake of underestimating rising star Tszyu.
