Farrell guided the IBF heavyweight world champion to a dominant knockout win in the world title bout last month and was shocked at how Dubois was able to repeatedly floor his opponent before the contest was stopped in the fifth round.

The coach told BoxingScene.com: "We did it relatively easier than we thought we would do it, I’ll be honest with you.

"But we’ve been there every day, dedicated to this. We were on Don's (Charles, head trainer) farm every day for 12 weeks and Daniel put the work in. You do something every day for that length of time and it can get boring, but the enthusiasm Daniel has for training – he doesn’t show that. It’s great. He enjoys it. They say a happy fighter is a dangerous fighter and you saw proof of that against Joshua."

A rematch between the pair has been suggested but Farrell thinks that Joshua would be making a big mistake were he to step in the ring with his conqueror again.

He said: "If I was advising Joshua, I wouldn’t be telling him to jump back in with Daniel Dubois – a young, hungry, 27-year-old lion.

"What I see day in, day out, I know what he is capable of, and Joshua does too now. If Daniel has somebody hurt, they ain’t going to see the final bell. He’s a devastating puncher and I’m only talking facts here. He’s like a modern-day Mike Tyson. But a bigger version.

"There are other fights there for Joshua. He can do the [Deontay] Wilder fight. That would be a good fight between two massive names who both need a big win right now. A win for either of them in that fight would give them a load of confidence. They’ve been linked together for a long time and are both now coming off defeats. It would make sense to do that fight."
