Frank Warren believes Tyson Fury can make the necessary changes to win his rematch with Oleksandr Usyk.
The two fought earlier in the month, with the Ukrainian earning a split-decision victory that might have been brought to a close earlier when Fury was teetering in the ninth round.
There is a clause for a rematch and both heavyweights seem ready to run it back.
Speaking to Sky Sports, Warren thinks that the Briton can be a better fighter in the second.
"I think he can, he believes he can," he said.
"The truth of the matter is there was a point in the fight, I think at the end of the seventh round when he caught Usyk with a couple of really good uppercuts and he was struggling a bit, but he went back to the corner and found a second wind and came out and caught Tyson with a really good shot on the nose.
"It seemed to trouble Tyson a bit, it took his momentum away a bit, obviously we know what happened in the ninth.
"It was a fight of two halves, Tyson knows what he has to do and I'm sure Usyk does. Both of those guys were in an absolute war that has taken a lot out of both of them.
"It will be interesting to see when it does happen who it has impacted the most."
