Chris Eubank Jr has called for "low-life" rival Liam Williams to retire as he accused him of fighting "dirty".
The pair exchanged regularly ahead of their middleweight tilt last weekend with Eubank Jr unhappy with some of the comments his rival had made in the build-up.
Eubank Jr secured victory over Williams after cruising to a decision having scored four knockdowns in the contest.
Despite the pair having now shared the ring together, Eubank Jr has revealed he refused to shake the hand of Williams and believes he is still "bad for the sport".
"Absolutely not, he is still the same low-life he was before," Eubank Jr told Mirror Fighting . "He fought an extremely dirty fight, bad for the sport and bad for boxing, I hope he retires.
"You have kids watching that hearing the things he is saying and watching the things he is doing with the head-butting and head-locking. Everything that he was doing was disgusting and the referee did nothing.
"Kids are looking at that and thinking 'if he can get away with doing that and not getting a point taken away, so can I'. I didn’t shake his hand or speak to him after the fight.
"I showed him as the fake that I said he was. This was a first for me because the things he said about me during the fight was personal.
"Until there is a public apology I won’t be showing him respect, just because we shared a ring it doesn’t mean we should shake hands?"
Eubank Jr will now target a number of options for his next opponent which include his favoured choice of a world title shot against Gennady Golovkin.
This could be a challenging ask however with Golovkin expected to favour a unification bout with Ryota Murata which has already been delayed once.

Another option could be against Billy Joe Saunders who has now offered to take on his previous rival in a second meeting after his victory over Williams.
Eubank Jr has now suggested that the option against Saunders could realistically happen "next" if a world-title shot remains unavailable.
"To be honest that fight could happen next," Eubank Jr continued. "If we can’t pin down the world title fight, that is a fight that could happen in the summer.
"That is certainly a fight that could happen this year if we can come to the agreement. He is in no position to be demanding and setting rules up.
"Canelo took away everything he had and that was his belts and credibility. The only thing he has left in boxing is me, so that fight will happen but it will happen when we are ready.”
