Tyson Fury's dad insists he will be supporting Anthony Joshua this week as he takes on Francis Ngannou ahead of a potential fight with the Gypsy King.
John Fury has heaped praise on Joshua as a fighter and says people should 'not forget' what he has achieved so far in the sport.
Joshua and Ngannou will enter the ring in Riyadh, Saudi Arabia on Friday evening in a much-anticipated heavyweight encounter.
The Brit will be fighting for the fourth time in the space of 11 months as he attempts to get his career back on track following successive defeats to Oleksandr Usyk.

Joshua wants to fight Fury after his undisputed clash against Usyk in May but must first get past Ngannou.
Fury senior seems keen to get the fight on between his son and Joshua, telling Queensbury Promotions: "Let's get it on boy!"
The 59-year-old wants Joshua to beat Ngannou after the Cameroon-born fighter caused his son problems five months ago.
But he has warned the former two-time heavyweight champion not to take his opponent lightly.
John Fury added: "Listen, I want him to win, he's a Brit. I'm rooting for him, I know he can do it.
"I've always said the best is yet to come from Anthony Joshua, he just needed the right cornerman to get his mind right.
"I think the only times he has struggled is through mental problems, not his ability. Big, strong man, he can punch, he's got quick hands, his stance is alright.
"I think AJ has learned on the job as well you know. He's a better fighter now than what he was three years ago.
"But the thing is Ngannou, his trainer spoke to him, very tricky, they've taught him to offset fighters, keep them busy.
"He looks like he's working when he's not. It can be made difficult if AJ doesn't keep it simple."
Fury met Joshua in Riyadh on Monday and afterwards he paid tribute to the impact he has had on boxing, as well as giving further advice ahead of facing Ngannou.
He told Sky Sports: "He is a f****** big fella, isn’t he? I've always liked Anthony Joshua, I've never said anything wrong about him.

"He's a great fighter, Olympic gold medallist, he's done a lot for boxing, let's not forget that.
"He is a good fighter and he will be a world champion again, but I couldn't get over how really big he was, the man's a unit! He's always been a nice guy, a respectful man, he showed me respect.
"He was lovely and it was heartfelt. I've got nothing but admiration and respect for Anthony Joshua, it was a great moment for me.
"If he boxes properly, keeps his head, sticks to a game plan, he will win on points.

"If he mixes it with a big puncher, Ngannou's a unit, he's had Tyson on the floor, Tyson said he can really bang, probably the hardest he's been in with including Deontay Wilder.
"He's got to be careful, but AJ has got the skillset, he's got the power of himself and who knows, he has this effect on fighters doesn't he? They just melt in front of him... don't rule [out] an AJ knockout either, but it's gonna be AJ on points I think.
"Ngannou's a strong man and he's a man with belief in himself, he's super fit, 19 stone, he's got to be careful as well."
