Sam Sexton did nothing to harm his British title claims when he forced the man nicknamed The War Machine to sign a surrender treaty as their phoney conflict finally came to an end.

Sexton's six-round points demolition of Larry Olubamiwo – two years after the Norwich man won a countback decision after their first meeting ended early after a clash of heads – meant the show title, Unfinished Business, was quickly changed to, Business Concluded.

Olubamiwo is unlikely to darken Sexton's door again, with the 29-year-old heading back to Austria at the end of the month for a second training camp with the Klitschkos. Those boys don't work with mugs, and Sexton is no mug – he knows that rubbing shoulders with the best will help his own A Game.

'It happened earlier on in my career when I was just starting out,' he said. 'I was sparring with people like Danny Williams and Matt Skelton, who were on top form at the time and I thought it brought me on a few years.

'When I went sparring with the Klitschkos. Someone said to me it will either do me the world of good or it will make me decide whether or not I wanted to carry on. I went over there, I had the time of my life and it was the best thing that could have happened. I saw how they train, how they do things and had three weeks of chilling out – when I am in Norwich it is 100mph, what with running my business as well.'

Trainer Graham Everett has organised sparring with the likes of David Price, John McDermott and Tom Little in preparation for Saturday's fight, at The Epic Centre.

'Working with the Klitschkos takes him up a level – he did a great job last time and they want him back.'

Sexton was in control from the start on Saturday, the left jab working well and snapping Olubamiwo's head back on numerous occasions. But it was the right that did the big damage in the second, when Olubamiwo faced a standing count, and even then looked shaky on his feet. Olubamiwo survived the round, but it might have been a different story.

'Everybody tells me I have one of the best jabs in the business so I thought I would prove it to myself,' said Sexton. 'When I did knock him down I felt my hand go a little bit so I had to step off a little just to see the rest of the fight out really.

'He is a big solid man and anyone that size is very dangerous and you have to be careful - he is physically strong as well, when you are pushing each other around you can feel the size and the power.'

Everett added: 'It would have been nice for us to get him out of there but it was a good fight. Larry is always dangerous - a big man with big punches, but Sam worked well and got his jab working.'

There was a 13th win in a row for Nathan Dale, who showed plenty of maturity against Lewis van Poetsch, who did his best to stay out of the Norwich man's way for six rounds. It was a tactic that saw him survive, but didn't go unnoticed by the official who gave a frustrated Dale, not surprisingly, every round.

'All in all I have to say, nights like that, grassroots boxing, is what we enjoy,' said Everett. 'Nathan is ready to step up to the next level, as we all saw. It was a good crowd and I think everybody enjoyed it – having Sam and Larry at the top of the bill was really good.'
