John Fury is concerned his son could become 'stale' during his training camp for the undisputed clash against Oleksandr Usyk.
Tyson Fury chose to arrive early in Saudi Arabia ahead of the mega February bout, which his father thinks was the wrong decision.
Fury flew to the Middle East on New Year's day, more than six weeks out from the fight.
His dad is not a fan of the plan and believes he should have stayed in the UK until the end of January to be surrounded by home comforts.

Fury senior told the Daily Mail: "I would have gone to a rural area. District, South Wales or the Peak District.
"Somewhere you can get some solace and some proper fresh air, running up the hills in all weathers at 5am.
"Then I would have gone to Saudi two weeks before, two and a half weeks before. But, the grinding could have been done here.
"When he beat [Wladimir] Klitchko, he was running over the hills at Lake Windemere.
"He was doing sprints and all kinds of grueling work up and down those hills.
"He was doing the circuit training. Everything but the kitchen sink.
"I don't think that will be possible from the hotel in Saudi."
John Fury admits being in the same place for more than six weeks could affect his son's mental state heading into the fight.
He added: "You can't beat working out in the fresh air. You can't beat sprinting up the hills. He could have even gone to Tenerife.
"Whether being in the hotel for two months will make him go stale or stir crazy, I don't know.
"It's the same thing every day. But, if he was here, there is something different to see every day.
"The same scenery can take the edge of you sometimes, you can get sick of being there.
"Then you end up grinding in another way you don't want. You get bored and you start thinking, I could do with not being here, I wish this was over.
"South Wales would have been a great place. There is no place like home.
"All the greats like Muhammad Ali all trained at home."
