Step in WBO number one contender Tim Tszyu who is hoping to follow in the footsteps of his great fighting father Kostya in becoming a decorated world champion.

Tszyu, unbeaten in 19 fights, comfortably beat Steve Spark 12 days ago and set his sights on a step-up in class against someone like former WBO champion Liam Smith.

Tszyu’s promoter George Rose said he would speak to WBO President Francisco Valcárel about making ‘The Soul Taker’ the mandatory challenger for Castaño’s title.

Speaking to Fox Sports Australia Ben Damon, Rose said: “We’ll talk to Paco at the WBO today about the prospect of making Tszyu mandatory for Castaño’s belt and we’ll be doing everything possible to make that fight happen before the end of the year.”

Not long after Saturday night’s result Tszyu took to Twitter and said: “Congrats Brian Castano. I’m ready when you are…”

“I thought Castaño won but that fight is over now and I know I have the style to beat him,” Tszyu told Fox Sports Australia.

“Like I said, I’m ready when he is and I believe I will stop him – he is tailor-made for me.”
