Anthony Joshua is refusing to get rattled by rival Dillian White ahead of their British and Commonwealth heavyweight title clash next month.

The Watford heavyweight was beaten by White as an amateur in 2009 and the pair will have a rematch as professionals at the O2 on Saturday, December 12.

His opponent has consistently attempted to get under his skin and placed his hand on Joshua's chest at Tuesday's press conference.

But Joshua kept his composure under the spotlight and is focused on extending his professional record to 15 knockouts from as many fights.

The 26-year-old said: "It's just like the rest of the fights I've been in. I'll approach it with the same attitude that I've approached the other fights in my professional career. I don't want to try and do anything too over the top.

"I'm trying to step up the ladder. For the British title, whether it's against Dillian or anyone else, I'll approach it with the same attitude and the same hunger. There is attention around this fight, which gives us the more reason to go for a 12-round war."

Joshua has never been past three rounds but the heavyweight is prepared for the possibility of a longer fight against unbeaten White.

He said: "It may not go the distance but I'm sure Dillian is potentially the man to take me past three rounds. It'll be tough for him to do that, though, because I'm going to be ready."
