'I think you can either become overwhelmed or perform under pressure - it’s either or,' he told Sportsmail exclusively at the launch of Lucozade Sport's partnership with Our Parks, which will hold free fitness classes in more than 30 London boroughs.

'I think I'm at a stage now where I don't know everything but in terms of being thrown in the deep end, with the [Wladimir] Klitschko and Takam fights, how I felt with the Klitschko bout is different to how I felt for the Takam fight and it should be different for the Parker fight due to experience.

'It will be interesting to see how he copes as it is daunting. It is showtime and everyone is watching now. It's not only the fight night, remember it’s the whole build-up in terms of the press conference, the fight hype, the build-up and the interest — everything will probably be bigger than what he’s used to.'

The build-up to the fight has already begun with Parker's trash talk claiming Joshua is the 'king of steroids'. He has since apologised for that slur but it is another in a line of derogatory remarks Joshua has faced from his opponents who have tried to get under his skin before a fight — all to no avail.

'They've got to be who they are but sometimes I think that they do it for an act.

'Klitschko was straight up. There wasn’t too much trash talk or disrespect but he got his message across that he's obsessed with winning and so on. He talked about raising money for charity and he said that when he beats me he’ll help guide me back to the top.

'He said his little sly remarks but they weren’t like "Anthony’s a bum… he can't perform." That’s why I’ve always said I respect Klitschko but some of the other heavyweights I don't.

'That’s just my opinion. If that’s their way of trash talking you can say what you want but it doesn't affect me as I don’t respect you anyway. You can’t really take in what someone says if you don’t respect them.'
