The 28-year-old currently holds three of the five heavyweight titles, having this year added the WBA and IBO belts to the IBF belt he won in 2016.
He aspires to become the first boxer in history to hold all five titles and thinks a deal to fight WBO champion Parker in the next few months is close.
What I think can be a the truth is, I need to battle for the other title belts,’ Joshua revealed to BBC Five Live’s Sportsweek program when approached what his desire are for 2018.
‘There’s just two remaining, I have three. There’s five on the table and I have three of them, I need to battle for the fourth one, the WBO heavyweight title of the world.
Transactions are intense, yet, as far as the adoration for the game, I won’t let that act as a burden from accomplishing my objective since heritage is imperative to me and I believe we’re accomplishing something that… To hold each of the five belts has never been done, so I won’t let arrangements hinder securing my heritage and what I could accomplish in the game.
‘I believe we’re 95 for each penny of the path there with finishing with Joseph Parker.’
At the point when asked when a battle with the New Zealander would happen and in the event that it would be on British soil, Joshua included: ‘End of March, I would state.

He has his own particular fights and evil spirits to confront and, once he has over them, he’s more than welcome to enter a ring with me. It’s something that we ought to concentrate on in 2018.
