Trainer Bobby Rimmer has urged champion Brian Rose to pile on the power much earlier.
The Blackpool boxer left into the 12th round to mount his most ferocious attack on Joachim Alcine at the Winter Gardens, and it paid a rich dividend, forcing a stoppage and earning Rose the World Boxing Organisation inter-continental title to add to his British championship.
But Rimmer says he wants Rose to implement such forcing tactics well before that.
Rimmer said: “I told Brian at the start of the 12th round against Alcine that he had to put his mark on the fight.
“Brian has got this thing in his head sometimes from his amateur days that he has to save a bit – but he doesn’t have to do that because he is super-fit.
“That is what frustrates and annoys me sometimes – I know he can step on because I know how fit he is.
“He is going to have to put his foot on the gas in the first, second and third round, instead of waiting for the end rounds.”
But Rimmer said he was proud of the win over Alcine, a former World Boxing Association world champion at 11-stone.
Rose’s coach said: “Brian has boxed a world class operator –everybody thought Alcine was passed it because of what Matthew Macklin had done to him the fight before, but he wasn’t passed it and at times he ‘old-manned’ Brian out of it a little bit.
“He caught Brian with a good shot in the ninth round – Brian showed how good his chin is.
“He came back to the corner a bit dazed, but after 10 to 15 seconds he was right back on track.
“Brian might have had a rude awakening in the ninth round.
“He has dominated the domestic scene so well, and now he has thought to himself this is what it is like (at world level).”
Rose is expected to be back in the ring in early summer.
Rimmer said: “He will be out in June and probably against another world-class opponent - who that will be is up to Eddie Hearn, his promoter, as I am just the trainer.”
Meantime, Blackpool cruiserweight Matty Askin is spoiling for a re-match against Jon-Lewis Dickinson for the British title.
The pair have already met for the English title, but Dickinson won convincingly, with Askin completely failing to rise to the occasion - Dickinson has gone on to become the British ruler.
Askin’s manager Paul Speak said of Saturday’s English title victory over China Clarke: “It was a big win for Matty – it has built his confidence back up.
“Chris Keane is his mandatory challenger for the English title, and it has been put in for purse bids by the British Boxing Board Of Control and we will see what happens with that.
“I would like to get him that re-match with Dickinson – either way that was a massive win for him and it has boosted his confidence.
“Matty is kicking himself for what happened in the Dickinson fight, but now he is showing that he has what it takes.
“He is not afraid to fight anyone - the cruiserweight division is open.
“There is no-one to be fearing, but he is English champion and let him just celebrate that and savour that - Blackpool should be proud of him.”
