Joseph Laryea is in for "one big shock" when he comes face-to-face with Ricky Burns in their WBO super-featherweight title fight on Saturday night, according to the champion's trainer, Billy Nelson.
The two boxers met head-to-head at a press conference in a Glasgow city centre restaurant on Thursday ahead of their clash at the Braehead Arena.
The Ghanaian made a 'slit throat' gesture as he posed with Burns for photographs, while one of the challenger's lively entourage delighted in showing off his betting slips which revealed the large sums of money he had placed on their man to beat the Coatbridge boxer by a knockout.
However, none of the bravado emanating from the challenger's camp impressed Nelson.
"Joseph Laryea has never fought anybody like Ricky Burns," he said.
"He is in for one big shock on Saturday night.
"Ricky has speed, accuracy of punch, and his power is developing fight by fight.
"He has a water-tight defence and amazingly fast hands.
"I know he doesn't like me blowing his trumpet but you haven't even seen the best of Ricky Burns.
"There is a whole lot more to come from him, that's all I am going to say to you and hopefully Joseph will see it on Saturday night.
"And if he sees the best of Ricky then there is absolutely no chance he is going home with that belt."
Nelson continued: "Ricky will put on a good show on Saturday night.
"He is improving week by week and he has grown in confidence in each and every fight.
"So I look forward to him showcasing his talents.
"If Ricky Burns produces 85 per cent of what he produces in the gym, then the crowd will sit up and take notice."
The African beat Paul Appleby at the same venue in December, on the undercard of Burns' first defence of his belt against Andreas Evensen.
Laryea is still bemused at how one of the judges had given the South Queensferry boxer the fight in a split decision, but he is adamant Saturday's title challenge will end with a knockout one way or the other.
Burns will simply be happy to hold on to his belt.
"Whether I win by points or knockout, it doesn't really bother me," the champion said.
"But there is no way that I am losing that title.
"I don't like all the hype. I want to get in the ring and do my talking.
"If you go out looking for a knock out it doesn't happen.
"Whether I look good or not, as long as I win. That's what it is all about.
"All the work is done. I have been ready for the last couple of weeks.
"Now I am just playing the waiting game.
"I am taking nothing for granted. I know that I am in for a hard fight but hopefully I can get in there and do the business."
Stephen Simmons, 2010 Commonwealth Games bronze medallist, makes his professional debut at cruiserweight against Londoner Nick Okoth.
The Edinburgh boxer said: "I am looking forward to my pro debut.
"It has been a long time coming and I can't wait to get in the ring.
"I am nervous but I have been fighting at the top level in amateur for the last five years so I will go in and do what I have to do and it should be no problem
"I will just be looking to get the job done and get on to the next fight."
