Kell Brook is targeting surpassing Floyd Mayweather Jr's 49-0 unbeaten record.
The IBF world welterweight champion has beaten Jo Jo Dan and Frankie Gavin since wresting the title from Shawn Porter in 2014, and Brook, who is currently 35-0, wants to extend his record beyond Mayweather's.
"[Mayweather's] 49-0 record is incredible," BT Sport quotes the Sheffield fighter as saying.
"His record is incredible and he leaves a phenomenal legacy, but I believe that I can reach the pinnacle and go past."
Mayweather announced his retirement after beating Andre Berto last week, and Brook gets a chance to close in on the American's record when he meets Diego Chaves in his next fight on October 24.
