Tyson Fury says he may retire after his heavyweight world title fight against champion Wladimir Klitschko, which takes place in Dusseldorf on November 28.
The 27-year-old undefeated British boxer will be hoping to defeat the Ukrainian for the first time in eleven years and claim his WBA, IBF and WBO belts.
In an interview with BBC Sport, Fury hinted at retirement saying that after the Klitschko bout he would have few challenges left.
"After this fight I won't have anything else to achieve and I'm on to a new part of my life," Fury told BBC Sport.
"If I've not got the motivation to carry on anymore then what would be the point?"
Fury added that he felt that the 39-year-old Klitschko could also be battling to stay motivated after having accomplished everything in the division and being the champion for many years.
"He's got tons of money; he's been successful for 11 years as a champion. What more does a man need? That's what's going to let him down on the night," he said.
"But you've got to give him credit where credit is due because to take on a young, ambitious guy like myself who's taller, bigger, faster, younger is a challenge in itself."
