Ricky Burns admits the only footage of Jose Gonzalez he can find is of his WBO lightweight challenger knocking opponents out.

But the Scot is not too concerned about his rival's impressive KO ratio of 17 from 22 victories.

The 30-year-old Coatbridge fighter, who defends his belt at Glasgow's Emirates Arena on May 11, believes his own improving punching power can act as a deterrent.

"We have been struggling to get any footage of his fights – the only things we can find on YouTube is him knocking boys out," Burns said.

"He is obviously a big puncher but I have been in with big punchers before.

"I will just have to make sure my hands are up and I go out there and do what I have been training to do.

"His knockout ratio doesn't concern me at all."
