Ahead of Tyson Fury’s epic heavyweight showdown with Anthony Joshua, his co-trainer Andy Lee believes that the delays to the unification bout have “frustrated” Fury and he doesn't know whether the lay-off will be beneficial or detrimental to the Gypsy King.
Fury was last in action more than a year ago, beating Deontay Wilder by TKO in seven rounds in Nevada last February.
"He is frustrated," Lee, who is also Fury’s second cousin, told Sky Sports. "The end-date was February, then it was March, now we're still going on.
"He's very frustrated that the biggest, most powerful people in boxing can't seem to get the deal done for whatever reason."
Asked if he was worrying that the fight would fail to materialise, Lee said, "It's inevitable that it will happen.
"But all this sitting around and waiting? Tyson could have fought in February or March. He's been held up by it. He does like to be active.
"I don't know if it's to his detriment or his benefit that this wait has happened.
"He will be ready to unleash the fury when this fight is on!"
Tyson Fury has been in working hard in Las Vegas alongside head trainer Sugarhill Steward and Lee in preperation for Joshua, and the former WBO middleweight champion says that Fury has been relentless in his training for the undisputed title fight, which is shaping up to be the biggest bout in British boxing history.
"He hasn't stopped training, he hasn't skipped a beat," Lee said.
"He trains hard anyway. He pushes himself further and further every day.
"You think: 'Where is the ceiling?' But he keeps going and going and going.
"He took the lads up Mount Charleston - Badou Jack, Jesse Magdaleno, some other Mexicans. But they all quit on him. He did seven miles up this mountain, pushing so hard.
"He is physically in great shape."
