Underdog Amir can hit the jackpot in Vegas, says Lennox Lewis
Lennox Lewis has stressed the difficulties Amir Khan would have had to overcome to rebuild his reputation and secure tonight's big fight in Las Vegas with WBC middleweight champion Saul 'Canelo' Alvarez.
The 29-year-old Khan - considered a huge underdog - has twice suffered heavy knockout defeats, by Breidis Prescott in 2008 and Danny Garcia in 2012.
Khan's improvement since switching to trainer Virgil Hunter after the Garcia defeat is similar to Lewis after the heavyweight recruited Emanuel Steward having lost to Oliver McCall, and the retired world champion said: "What it takes to come back from a knockout is the worst.
"You have a lot of people saying 'Does he still have it? He has a glass chin'. Rumours always follow you around.
"If you're the loser, that takes away a bit of your energy. You have to build yourself up mentally, and say 'No, this is not me, I want to prove that I'm the best in the world'. It's about reconnecting mentally.
"Everybody has to get that trainer they're comfortable with."
Meanwhile, Floyd 'Money' Mayweather could be set to come out of retirement to face Dublin's UFC king Conor McGregor in the richest fight in boxing history.
Mayweather will pocket £100m while McGregor will pick up £7m for the Las Vegas mega-fight.
