He may be just a few days shy of his latest world title defence but Kell Brook could hardly have a cut a more relaxed figure during a public workout on Fargate.
The IBF world champion even invited a couple of young fans into the ring for an impromptu sparring session as he puts together the final preparations for his defence against Frankie Gavin on Saturday night.
Six-year-old Oliver Blackwell from Norton was one of those who climbed through the ropes and laced up the gloves, looking to playfully rough up Brook in front of a few hundred spectators.
“He was swinging for the houses,” Brook said of Oliver.
“We want to get the fans laughing, get them behind me and get the kids in here.
“The city of Sheffield turned out and I want to thank everyone for coming out.”
While there was plenty of laughing and joking as he showed off his skills to the Sheffield public, Brook insisted he is not taking the challenge of Gavin lightly.
The Wincobank welterweight is the overwhelming favourite to win at London’s O2 arena on Saturday but says he has left no stone unturned in his preparation.
“Dominic Ingle (trainer) has seen it all before and we’ve got our eyes firmly on Frankie Gavin,” Brook said.
“We’re not looking past him and every time we’re in the gym he’s pushed me hard and we’ve done what we needed to do in camp.
“I’m fully focused on him and fully prepared.”
Though keen to acknowledge the danger posed by former world amateur champion Gavin, Brook remained in confident mood and predicted that he would stop the Birmingham fighter.
He said: “If I catch him with a chocolate brownie right hand in the first round it’s going to be over.
“You don’t get paid overtime in boxing so whenever I hurt him I’m going to jump on him and finish him.
“I’ve trained for 12 hard rounds and I’ll take whatever comes first.”
