Josh Warrington says he is ready to take the "next big step" in his career by beating Joel Brunker in Leeds on September 5, live on Sky Sports.

Warrington, who enters the fight with a perfect 21-0 record, is aiming to defend his WBC International and Commonwealth Featherweight titles against the 29 year-old Australian.

Brunker returns to the UK for his first bout since losing to Lee Selby in an IBF world title eliminator at the O2 Arena last October - his first professional defeat.

Warrington, 24, admits that he cannot afford to underestimate his opponent, who held a record of 27-0 prior to the Selby fight.

"I need to prove I can mix it with the likes of Joel Brunker so I can show that I am ready to take the next big step to a world title," said Warrington.

"I've been asking more of myself in training because I know I cannot go in there a 99 per cent - I have to be 100 per cent to beat him.

"The next belt in my progression is the world title. There's no point me kidding myself and boxing tin cans, I have to be boxing people like Joel.

"He is coming over to prove he is a world-class fighter and he's going to bring everything he's got.

"You don't get a record like Joel's without being a quality fighter. He's got a great work rate, he throws a lot of punches and he's definitely the biggest name on my CV.

"I've come a long way, the more the profile rises, the more the pressure rises. I'm loving that pressure."
