Richie Woodhall is not one for making bold statements so when he declares that Frank Warren's new signing is a world champion in waiting it would be wise to listen.
Thomas Costello has left Ken Purchase's Ringside Promotions stable to link up with the biggest promoter in Britain on a four-fight deal.
With Amir Khan and Joe Calzaghe already on his books along with another vaunted pugilist from Birmingham - Don Broadhurst - Costello is mixing in exalted company.
However, the icing on the cake is that he will continue to showcase his undoubted talents in Birmingham and he appears on Pugilist Promotions inaugural show at the Custard Factory on Sunday.
The 18-year-old welterweight is being groomed for stardom by his renowned father-trainer John Costello.
Woodhall worked at close quarters with Costello during his embryonic days as a professional and is suitably impressed.
He successfully defended the WBC title during his heyday and believes Costello will follow suit.
"I fully expect Thomas to be world champion one day - he is that good," said Woodhall. "If he had stayed as an amateur then he would definitely have been fighting in the Olympics in London in 2012.
"However, now he is a professional, I would expect him to be competing at world-class level as he is a really talented kid.
"The four-fight deal with Warren is great news as he will really be in the limelight and no doubt appear on the Amir Khan shows.
"It is a fantastic stage for him and whilst it is almost like a trial, I have no doubt that Frank Warren will sign him up once again when this deal has finished. He is that good."
In fact, Woodhall banged the drum with gusto on Costello's behalf after being quizzed by Warren's matchmaker.
"I know Dean Powell really well," added Woodhall. "He asked me about Thomas and I told him what a good kid he was and I think that reassured him a bit.
"Dean respects my opinion and I know Thomas will benefit from this move.
"When I first met him I told him that I thought he should stay as an amateur until the Olympics but I think he had fallen out with the England set up and his mind was made up.
"He can bang a bit and has good boxing ability and his dad (John) has certainly does his homework.
"He is in safe hands with John who is a successful amateur coach and making the step up to the pro game well. John has great knowledge but he will still seek my advice occasionally over durability and other things and I am always happy to help.
"That kid will definitely be a world champion."
Pugilist Promotions debut Birmingham show will take place at the Rojac Building, Custard Factory in Digbeth on Sunday.
The afternoon show will feature Costello, Eddie McIntosh, Tom Owens and Delroy Mitchell.
