WBO super featherweight champion Vasyl Lomachenko (7-1, 4KOs) has no problem with moving in weight to challenge Terry Flanagan, who holds the WBO's world title at 135-pounds.

Lomachenko has already captured world titles at 126 and 130. He wants more.

On Saturday night he retained his title with a seven-round demolition of Nicholas Walters. The fight came to an abrupt end when the Jamaican fighter told referee Tony Weeks before the start of the eighth round, "I don't want to continue."

Two-time Olympic champion Lomachenko registered the biggest victory of his career in dynamic fashion as it was the second defence of his title and just his eighth professional fight. With his victory Lomachenko - who compiled an amateur record of 396-1 with Olympic gold medals in 2008 and 2012 - is now 7-1 as a professional.

Also on Saturday, but in Cardiff, Wales, Flanagan (32-0, 13KOs) retained his title by dominating and stopping Orlando Cruz in eight rounds.

Prior to the fight, his promoter Frank Warren discussed the possibility of matching him against Lomachenko next year. Flanagan wants that fight to happen.

According to Warren, he's spoken to Lomachenko's promoter, Bob Arum of Top Rank. But before Flanagan can get too excited about Lomachenko, he must first face mandatory challenger Felix Verdejo, who is also promoted by Arum.

"I've been talking to Bob Arum and I think it would be a great fight to put on in Manchester - maybe at Manchester City - either in the spring or summer," said Warren. "I've made no secret of my admiration for Lomachenko or for Terry who I think is one of our better world champions - it would be a tough fight but as I've always said I think Terry thrives on tough fights and I think the harder the fight the more you will get out of him."

Lomachenko wants to do the fight - but NOT in the UK. He feels the contest should be conducted in a neutral country like the United States.

"Why England? Why would I fight Flanagan in England? Why do I have to go to Britain? Why don't we do it here? Come to a neutral site. The mecca of boxing is the United States, I'm ready," Lomachenko said.
