Deontay Wilder will have 'big problem' if he fights Derek Chisora, says Brit heavyweight's former trainer Don Charles

Deontay Wilder will have a 'big problem' if he decides to return against Derek Chisora, say the British heavyweight's former trainer Don Charles.

Chisora is expected to have his 50th and final professional fight this year and the 42-year-old has been linked with a explosive encounter against Wilder, the American former WBC champion.

Since defeating Otto Wallin last February, Chisora has been considering his options, which have included a trilogy fight against Dillian Whyte and a WBO title fight against Fabio Wardley.
