Tyson Fury claims he could be looking for a new trainer following an apparent fall-out with uncle Peter Fury.
The WBA Super and WBO heavyweight world champion says a conversation took place after he was knocked down in sparring, in which he was told to "sort his head out" ahead of the rematch with Wladimir Klitschko.
Fury admits he is lacking motivation and following a recent sensational claim that he was about to walk away from the sport, he now suggests he and his mentor and trainer Peter will be at loggerheads if things don't change.
"Me and Peter have had a bit of a fall-out over the sparring," he told Sky Sports.
"He said to me, 'If you're getting knocked over by light-heavyweights, what's Klitschko going to do?'. He's left for a couple of days but I am not sure if he's coming back if I'm honest.
"He was talking sense really but I can't do much about getting knocked over and if he's not happy about it, I've got to adopt a new trainer. If he doesn't want to come back then I have to get someone else in.
"Peter said to me, 'If your mind isn't 100 per cent on it, you don't want to be in there and are just in it for money'. He said he wants no part of it 'because I don't train losers'.
"That's how he's left it and said he was going to come back next week and we'll make a final decision if he trains me or not.
"We've never got this far because I've always been motivated and always been raring to go, but in this one it's just like I'm going to the shops. I don't know what's wrong with me at the moment, I am just not performing.
"Peter advised me to quit for a couple of days until I get my mind right or don't bother at all. I think he's right but I've got bills to pay and mouths to feed and at the end of the day, it's my career and my choice."
It is not the first time Fury has suggested there were problems in the camp and before the interview, Peter Fury joked: "Apart from Tyson getting knocked out every five seconds, everything in the camp is great."
Tyson Fury, who admits he still has over 20kg to lose before reaching his target weight for the Klitschko fight, says the sparring was cut short following the now-infamous knockout.
He added: "I had some heavyweights come and just smashed them and he said, 'Box them first, use the jab' but I just steamed in there and put two out and he just said, 'That's clever, you've just lost us two sparring partners now'.
"I said, 'They shouldn't come here or be paid if they can't take a hiding'. He then brought in a light-heavyweight who is very quick and awkward and I just walked onto a couple and ended up on the canvas.
"That was it and after that he said to stop the sparring, I said 'no carry on' and all that sort of stuff, but he stopped it, sent the lads home then had this big conversation and this is where we are at.
Fury insists the latest claims are not an attempt to play mind games ahead of his Manchester showdown with Klitschko on July 9, despite Peter's claims that the heavyweight champion is "always on the wind-up".
"My dad said to me this morning, 'This is a god-send to Klitschko, he'd heard all this this morning and it would be music to his ears... camp going wrong, families falling out," he said.
"But [all] I am is being truthful, that's it really. Hopefully this will all be sorted.
"It's not ideal. It's right in the middle of training camp but it's happened before to other fighters and obstacles are for overcoming and if it happens, I think that is the one I've got to get over."
