Joe Joyce has claimed Tyson Fury is the most talented boxer he has shared the ring with.
"I am getting the best possible work right now, I feel better than ever sparring Tyson, making me a better fighter as he is the most talented I've been in the ring with, which brings the best out of me," he wrote on Twitter.
"You would pay good money to see these spars!"
The Olympic silver medalist is helping his fellow heavyweight prepare for his world title shot against Deontay Wilder on December 1.
