New Zealander Parker, the WBO heavy world champion, is set to meet the British boxing star and WBA and IBF title holder at the Principality Stadium in the Welsh capital.
And the 25-year-old Parker has stated that talks are at an advanced stage.
Speaking to ESPN, he said, “I think the Joshua fight can go ahead early next year when both teams are locked in and happy.
“When we can find a free date, a time in March, then we can definitely make it happen.
“Negotiations are going good. I think we’re close to locking something in. They’re stuck at 30 per cent (of the split), we’re stuck at 35 so it’s just finding the middle ground.
“We’ll take 35 percent which means Joshua will take 65, which is nearly double me, so I think that’s a fair deal because he’s the bigger draw card and he’s has two belts, and I have one.
“I think that’s reasonable and fair.
“I think we’re very close. I’m excited as it’s a chance to showcase my skills in the UK more.”
Parker and his camp are confident that they can cause a huge upset against the undefeated English golden boy once they finally get inside the ring.
