Tyson Fury has been widely scrutinised ever since his defeat to Oleksandr Usyk last month.
Some have questioned his passion and hunger after he suffered the first loss of his professional career at the Kingdom Arena in Saudi Arabia.
Others have been sceptical over whether he even has the courage to fight Usyk again, after losing to the Ukrainian on points.
However, it seems as though the 35-year-old still possesses the hunger and desire of old - despite seeing his copybook blotched in the Middle East.

Jorge Capetillo, Fury's cutman, has said he messaged the Briton immediately after his defeat.
And he says the boxing star made it clear he was eager to return to the ring and set things right when his second fight with Usyk takes place on December 21.
Speaking to Betway, he said: "I messaged him, and he is really good.
"Tyson said he was fine, back in the gym and is ready to rock and roll.
"He is ready to bounce back, and I know he will because he is a strong man. He should be able to bounce back from this loss and I couldn’t be more proud of him.

"He’s already conquered everything in boxing.
"He’s showed the world that anything can happen by coming back from his mental health to becoming world champion again.

Fury's fight with Usyk took place after months of delays.
But the bout lived up to the billing, with fans treated to a stunning show involving the two men.

And though Fury lost, Capetillo was impressed by the way the Gypsy King performed amid the heat of the battle.
"It was a great fight. In the beginning they were both fighting for the positioning, the distance and then Fury started getting the rhythm going and was outboxing Usyk from the fourth round," he said.
"Then you see the counter with a great left overhand and then a hook makes him start wobbling.
"But we know what Tyson Fury is made of, he has a huge heart and big balls.
"He was standing in the ring even if he was wobbling all over the place, but he was still up and continued to fight.

And his cutman is adamant he'll win, while also expressing a belief the fighter will make only minor tweaks to his game.
"I think the pace, keep his hands up a little bit more, sit a little bit more and not jump too much," he said when asked how Fury can come out on top.
"He can walk in instead of jumping and start boxing more, because he’s too big and heavy. You can jump for a couple of seconds but not for a couple of rounds.
"He needs to box more, keep his guard up and keep it tight. He’s the bigger man and he needs to push back Usyk.
"He was being efficient when he was pushing him back because he’s the bigger man."
