Eddie Hearn, promoter for IBF, IBO, WBA, WBO heavyweight champion Anthony Joshua, believes WBC champion Tyson Fury should be at ringside next Saturday night at SSE Arena in Wembley.
Joshua will return to the ring next weekend, after nearly a year of inactivity, when he faces mandatory challenger Kubrat Pulev.
Fans will be present, as an audience of 1,000 has been approved for the event.
Should Joshua win, he will be in line to face Fury in a huge unification clash in 2021.
In order to build that major fight up, Hearn would like to see Fury at ringside watching the action.
"I think that he should be coming," Hearn told Sky Sports.
"If he wants to fight Anthony Joshua, it's not a case of calling him out, it's called doing his research and building the fight. Tyson Fury is more than welcome to come down. I only live 45 minutes away from Wembley. He can come around on Sunday afternoon for a roast as well, if he wants and a cuppa.
"We just want to get that fight made. But first things first, we've seen it before at Madison Square Garden with Andy Ruiz when we were talking about the Wilder fight. This is it. This is the last hurdle - Kubrat Pulev, December 12."
Fury was scheduled to return to the ring in a stay-busy fight on December 5th. He postponed his return until next year.
While Pulev is the final hurdle for Joshua to move forward with the anticipated unification, there is one final hurdle that Fury must deal with.
Deontay Wilder has initiated a legal move to enforce his rematch clause with Fury.
Fury, who stopped Wilder in seven rounds in February, believes the rematch clause has expired. They were set to face each other back in July, with the fight being pushed back several times due to the coronavirus pandemic.
But, Wilder strongly feels the rematch clause is still valid.
Both sides are now taking part in a mediation to settle the matter.
