LEE Selby might be a world champion but Barry’s finest still has some big ambitions in boxing.

However, the IBF featherweight king knows he must get the job done against Jonathan Victor Barros in Las Vegas this weekend to give himself the best chance of fulfilling those goals.

The Welshman, 29, puts his title on the line for a third time when he faces Barros at the MGM Grand on Saturday night – the early hours of Sunday morning for those watching in the UK.

Experienced Argentinian Barros, a former WBA world champion, will be out to end Selby’s reign as the IBF’s number one, but the latter is more than ready to deal with whatever comes his way.

And holding on to his crown is not the only motivation for Selby to record a 24th career win from 25 fights.

Topping the bill in Nevada is a rematch between Northern Ireland’s Carl Frampton, the WBA super world featherweight champion, and Mexican Leo Santa Cruz.

There are high hopes that, providing Selby and Frampton do the business this weekend, the two will meet later this year – and that’s not the only thing Selby has in his sights for the future.

“It’s a very tough fight but it’s on the biggest stage in boxing at the MGM Grand in Las Vegas,” said the Tony Borg-trained ace.

“It’s a massive opportunity for me, my trainer and my manager, and I’m hoping to put on a good performance.

“I’m in great shape, I want to win and I want to look good.”

He added: “I can’t take my eye off Barros but I’m on the same card as Frampton-Santa Cruz and if we (Selby and Frampton) both win and look good then the fans will demand the fight.

“If it does happen I’d like it to take place at the Principality Stadium in Cardiff, that’s the dream.

“I’d like to try and unify the division and then maybe move up to test myself at a higher weight.”

Barros will take some heart from the fact Selby was sent to the canvas for the first time in his last outing against Eric Hunter – and the Welshman is well aware of the threat Barros could pose.

“He’s a big puncher and he’s very experienced, and I think he has knocked down more people than I’ve had fights,” he said.

“He can be very unorthodox so it’s going to be a tough challenge, but it’s one I’m looking forward to.”
