Anthony Joshua defeated Jermaine Franklin by unanimous points at the O2 Arena in London.
33-year old Joshua, in his post-fight comments, expressed unhappiness as he expected to knockout his American opponent in London.
However, another British heavyweight boxer, Dillian Whyte, believes Joshua is getting tired of boxing, saying “he doesn’t want to do it anymore”.
Whyte went ahead to advise Joshua to “stop” as he is losing “all his aggression and killer instincts”.
He said: “Joshua has lost all his aggression and killer instincts.
“If he doesn’t want to do it any more, I think he should stop.”
