Luke Campbell says he has gained strength from seeing his dad fight cancer and also by training alongside his hero Guillermo Rigondeaux.
The 2012 Olympic gold medalist at bantamweight (11-0, 9 KOs) faces old friend Tommy Coyle (21-2, 10 KOs), 25, in front of 20,000 at Craven Park in Hull on Saturday. Local pride is at stake between the two Hull boxers, with the winner also moving closer to a WBC world lightweight title shot.
In preparation for Coyle and what has been dubbed the Rumble on the Humber, Campbell has trained in Miami alongside world super-bantamweight No.1 Guillermo Rigondeaux, who has been linked to world title unification fights against Britons Scott Quigg and Carl Frampton.
Campbell, 27, found it an invaluable experience training alongside Cuban Rigondeaux who won gold medals at the 2000 and 2004 Olympics and then took just nine professional fights before he was WBA world super-bantamweight champion after winning the interim belt in his seventh paid fight.
"Rigondeaux is one of the guys since I first started boxing that I've looked up to and I was at the same weight as him for a while as an amateur, so to train alongside him was amazing," Campbell told ESPN.
"I've always watched him and studied him. I didn't spar with him, just trained alongside him at the same gym and it was quality to watch him. I believe he's the best pound-for-pound fighter in the world, I really do.
"It would be a tough fight for either Scott Quigg and Carl Frampton against Rigondeaux. He's too good for his own good though and that's why he's been avoided.
"Rigondeaux is an inspiration but not everyone is a Rigondeaux or [Vasyl] Lomachenko [the WBO featherweight champion]. I look up to both of them, they are both class fighters, but they are one in a million and you don't get many guys who can win world titles so early in their careers like they have."
Campbell has also drawn inspiration from his father Bernard, who is battling cancer.
"My dad is steady and battling away, showing a lot of courage," Campbell told ESPN. "It helps me focus and gives me inspiration knowing what my dad is going through and what he's battling and how determined he is to beat what he's fighting against."
