Ricky Burns will trust in his instincts when he meets Michael Katsidis for the interim WBO lightweight title at Wembley Arena tonight.

The tactics used by Burns will only be decided after the opening bell has sounded with the 28-year-old Scot believing adaptability will be key.

Australian brawler Katsidis will launch his signature all-out assault and Burns will trade with him if he must.

"I don't know what way I'm going to fight," said Burns.

"I've been working on a lot of different things in the gym, but in this fight I'll be operating on instinct.

"If the boxing is working I'll stick to that, but if the two of us go toe to toe, then that's the way it will be.

"I've seen Michael fight in the past but since the fight was announced I haven't watched any footage of him.

"I'm a believer that whatever happens on the night will happen. I want to concentrate on myself.

"Michael is a great fighter and he's proved that at the top level.

"Even though he's lost two of his last three he was only beaten by Juan Manuel Marquez and Robert Guerrero, who are at the top of their game.

"In my last few fights I've been getting more aggressive, but I can go back to boxing when I want to."

Katsidis is a major obstacle for Burns, who will be making his debut in the division having vacated his WBO super-featherweight title following three successful defences.

"Ricky Burns is in with the big boys now, but I'd say he realises that," said Katsidis.

"I'm established at lightweight so he can take on anyone from here, win or lose.

"It will be a tough fight. It's a brave move by him but it's risky for me too because he's an accomplished fighter."
