The Hornet already primes his sting, ready for Kostya’s boy.

Boxing champ Jeff Horn has begun training, ahead of his multi-million-dollar battle with Tim Tszyu.

‘The Hornet’ told the Courier Mail…he plans to break down Tszyu, with the type of pressure he used to win over Michael Zeraffa.

The bout is to take place in Perth in mid-April.
