Kell Brook has warned Carson Jones that he is a different fighter to the one who turned up in Sheffield just over a year ago.
The 'Special One' earned a narrow verdict in a bloody battle at the Motorpoint Arena last July, which saw him become number one contender for the IBF welterweight crown.
However, the American has a chance to put things right in a rematch at the Craven Park Stadium in Hull this evening.
Brook said that he is "bugged" by his performance in their initial bout, blaming poor nutrition and 'cutting corners' in training, but added that he has not made that mistake again.
"He was at 100% that night and I was nowhere near," the 27-year-old told Sky Sports News. "He's going to meet a very frustrated and angry man on Saturday.
"That fight bugged me because I knew I had let myself down and cut some corners in the build-up. I might have gone for someone easier, but I want to sort him out.
"I know he will be hard and test me, but I am in great shape and so ready for this fight. I have a lot of things to put right and I will make sure I do."
Brook brings an unbeaten 29-fight record to the contest, while Jones has suffered defeat in nine of his 49 bouts.
