Australian superstar Tim Tszyu is ready and willing to collide with Terence Crawford.

Last Saturday night in Las Vegas, Crawford battered and stopped Errol Spence in nine rounds to become the undisputed welterweight champion.

As BoxingScene.com reported late Wednesday night, Tszyu is about to be crowned the full WBO junior middleweight champion.

Tszyu is the WBO's mandatory challenger to undisputed junior middleweight king Jermell Charlo.

However, Charlo is moving up in weight by two full divisions to challenge undisputed super middleweight champion Saul 'Canelo' Alvarez on September 30.

The WBO will allow Charlo to enter the ring as world champion on the day of the fight - but Tszyu, who currently holds the interim-title, will be elevated to full-champion regardless of the outcome.

At the moment, there is no clear answer on whether or not Crawford will be available.

Spence has the option of exercising an immediate rematch clause.

Should Spence take a pass at a second fight, Crawford has already expressed interest in moving up to 154-pounds to pursue more titles.

And Tszyu is more than happy to face him.

“Ask him. Go ask him if he’s ready … that’s the real question,” Tszyu said to Fox Sports Australia.

“To be mentioned as the next fight for the number one pound for pound fighter in the world, that shows the level I’m at right now.”

Tszyu was very impressed with Crawford's performance from last weekend.

“Master class,” Tszyu said. "It was like watching a magician -- that’s what it felt like. And Errol Spence, he was all out of control. His balance was shot.

“The bloke was just, I dunno … he didn’t look right even before the fight. And immediately Crawford was in control. Countered everything, fought beautifully. Simple boxing.”

The unbeaten Aussie is also willing to face the loser of that fight, too.

In the aftermath of his defeat, Spence revealed that he intends to move up in weight to 154, but Tszyu doubts that fight would happen in the near future.

“So I’d still love to fight Errol Spence,” Tszyu said. “Looooove to fight Spence. But they won’t do it. It’s too much of a high risk fight for him. High risk, low reward. What does he get out of it?”
