“Yes, I can assure you of yes,” Arum told World Boxing News when asked if they were set for three bouts.

“There are a lot of good heavyweights who have had trilogies. This would be a trilogy.

“We’ve had great trilogies in the past. Ali v Frazier. Ali v Norton. They were all trilogies, not four fights.

“The percentages will change, as in the winner would get more on that third fight, than the loser. It’s all based on who wins the second fight.”

Manchester United manager Ole Gunnar Solskjaer says social media companies have to stop the spread of hate, after his midfielder Paul Pogba received racist abuse online last week.

Solskjaer is the latest figure from the club calling for stronger action, following defender Harry Maguire and striker Marcus Rashford. Former defender Phil Neville also suggested that players quit social media in protest.

“Social media is a place where Harry [Maguire] said people hide behind fake identities – it’s not down to me to change it,” added Solskjaer, who also said players would not be banned from using social media.

Last week, Chelsea condemned “abhorrent posts” aimed at Tammy Abraham after his decisive penalty miss in the Super Cup against Liverpool. Then on Sunday, Reading striker Yakou Meite called out racist abuse sent to him on social media after he had a spot-kick saved.

Earlier this week, Twitter stated it would meet United representatives and anti-abuse campaigners Kick It Out.

‘There’s no fighting between Pogba and Rashford’

Meanwhile, Solskjaer said he would not change his policy on two penalty-takers following the negative reaction to his tactics during the 1-1 draw against Wolves.

With the chance of going 2-1 up in the match, Pogba won a penalty and, after a discussion with Rashford, decided he would take the spot-kick. However, his effort was saved by Rui Patricio. A week earlier, Rashford had scored from the spot in the 4-0 win over Chelsea.

Solskjaer said: “I’m sure you’re going to see Pogba score a penalty for United again.

“Don’t be surprised if Marcus or Paul score the next one. There’s no fighting among them.”

The Norwegian also clarified the situation regarding the future of forward Alexis Sanchez, who has been strongly linked with a loan move before the transfer windows in Europe shut.

“There are still talks on Alexis with some clubs,” he added. “He played in a behind-closed-doors game – he’s working hard so let’s see in September.”
