Frankie Gavin is Britain's only ever world amateur champion and his only pro defeat came on points against Leonard Bundu in a European and Commonwealth title bout last summer. He has three wins on the bounce since, however, and his southpaw stance could prove awkward.

Known as Funtime, the man from the Midlands is on a mission to derail Brook tonight.

It's been happening since the dawn of time - two blokes preparing to scrap meting out a few choice words beforehand.

Kell Brook and Frankie Gavin were no different on Friday. What was interesting, however, was their body language. As they faced up to each other in front of the cameras, Brook seemed chirpy but composed while Gavin shook with adrenaline. He looked like he wanted to land one on the champion there and then.

He'll have to keep those emotions in check tonight. Adrenaline can make you tired very quickly if not harnessed in the correct manner.

Four-time world champion Carl Froch believes that Kell Brook is more focused on boxing than ever.

"I can only see Kell getting better and better now he's got that self-belief, and that means there will not be any sort of upset on Saturday night," he told Sky Sports., external

Kell Brook enters the ring tonight hoping to send a message to the rest of the welterweight division with a successful defence of his IBF world title against Frankie Gavin.

Unbeaten Brook, 29, had wanted a fight with Amir Khan only for his British rival to take a bout with American Chris Algieri in New York instead.

"I want to make the statement that I'm the man in this division," said Brook. "I'm looking to seek and destroy and prove I'm the number one in the world in the division."

Where does he rank? Should he be fighting the very elite in what is one of the strongest divisions in the sport?

How do you eclipse that? Well, we'll do our best with two Brits fighting for the world title: Kell Brook v Frankie Gavin.

Stuart Edward-Jenks: Sure I saw Buncey writing off Joshua a minute ago. Now he's the future......

Andy Gilderdale: Well, Kevin Johnson. How does it feel to be slapped into retirement by a "big baby"?

Paul Gibbons: One things for certain you wouldn't want to turn up late to a Joshua fight you'd miss all the action... sublime fighter.

Anthony Joshua, speaking on BBC Radio 5 live: "It shows I have the power but there were times when I was on the inside that I could have been more explosive. So far so good, but in the back of my mind I know it's going to get tougher.

"I'm going to stick with the people who have guided me to this point rather than fall into somebody elses' hands who thinks I'm the finished article."

Richie Woodhall
Former super middleweight world champion on BBC Radio 5 live

"He still hasn't been past four rounds. We don't know what he's going to be like over five, six, seven rounds. At one point when the referee didn't step in and I thought: 'is Joshua going to blow himself out?' because he hit him with so many hard punches. Is anyone out there going to stand up to Anthony Joshua?"

Anthony Joshua on Sky Sports Box Office: "I am here to try to make statements. My coach drills me in the gym and the hard work pays off. I want to dedicate that to my stablemates Kevin Mitchell and John Ryder - they've had tough nights tonight.

"The 'L' plates will come off when I face tougher opponents."

John Cotgreave: Anthony Joshua needs to take down Klitschko!!

Daniel Lewis: Anthony Joshua is just smashing through people. Is there anybody who can even match him?

Matthew Lynch: I thought Anthony Joshua was gonna be seriously tested tonight. I was wrong.

I wonder how that book's going, Kevin? (22:02)

Steve Bunce
Boxing expert on BBC Radio 5 live

"Stunning performance from Joshua. We went to a second round and I thought the referee should maybe not let him take this punishment. That was very impressive from Joshua.

"If we were watching this in the early hours of the morning from the United States we'd better getting very excited.

"I don't want the post mortem to say Johnson was too old and too fat. I thought he would go the distance. The look on Johnson's face was one of shock."

Steve Bunce
Boxing expert on BBC Radio 5 live

"We've seen the future and the future is Anthony Joshua. Let's not hear about Johnson being fat and overweight."

Let's just remind ourselves that Johnson had never previously been stopped, yet he's been in with Vitali Klitschko, Tyson Fury and Dereck Chisora among others. Joshua ended his night in the second round.

Joshua is the smiling assassin, he just stands there and belts his poor opponents until they give in or the ref steps in. Brutal power.

Joshua doesn't do overtime. In fact, he doesn't like to drag out his shift. But why not? He does his job magnificently. What a sensational fighter.

Joshua smiles and sticks out his tongue as he batters Johnson at will. There's nothing coming back. Another barrage in the corner and Johnson slumps to his knees. That's it! Joshua marches on with another incredible victory.

Mike Costello
BBC Radio 5 live boxing commentator

"If he goes down here he could well fall on top of us into our commentary position."

A lamb to the slaughter, Johnson staggers into range and Joshua is allowed to unload long, raking rights. Why has this not been stopped?

Johnson is back up and is again sent crashing by another Joshua barrage. The ref needs to help the American to his feet and to his corner. Saved by the bell. Lucky, lucky man.
