LISTEN: Lennox Lewis joins talkSPORT and discusses potential Floyd Mayweather v Conor McGregor super-fight

Lennox Lewis believes there is little chance of Floyd Mayweather Jnr stepping into a ring with Conor McGregor, but if they did he thinks the boxer would have too much speed for the MMA star.

Boxing legend Mayweather and UFC sensation McGregor have both talked up the possibility of a cross-sport super-fight.

It would be one of the richest events in sporting history and would likely earn both men well in excess of $50m.

But Lewis, the former undisputed heavyweight champion of the world, told talkSPORT on Tuesday the showdown is unlikely to happen.

"I don't think Mayweather would take that," the Briton claimed. "He'll run around too much, I don't think Conor McGregor would catch him.

"He's a fighter but Floyd moves so well he wouldn't want to get hit or choked out."

Lewis also gave his thoughts on the current crop of British boxing stars, including Anthony Joshua, Tyson Fury and Chris Eubank Jr.

Plus, he reflected on the life and career of his great friend and fellow former heavyweight world champion Muhammad Ali following his death in June.
