Amir Khan enters the “last chapter” of his career on Saturday night when he takes on Terence Crawford at Madison Square Garden for the WBO world welterweight belt.

Khan’s last world-title shot saw him suffer a brutal knockout to Saul Alvarez in 2016 at the T-Mobile Arena in Las Vegas after the Briton has made the step up to middleweight to face the Mexican fighter.

Since that loss, the 32-year-old picked up a TKO victory over Phil Lo Greco in Liverpool in April last year before clinching a unanimous decision over Samuel Vargas in Birmingham later in 2018.

The 2004 Olympic silver medallist will be fighting in Madison Square Garden for the first time this weekend, and, based on the enormity of the task, it could very well be his last fight at the venue.

Crawford is pound-for-pound one of the best boxers around and he boasts a perfect 35-0-0 record heading into the bout, with 25 of those victories coming by way of knockout.

He has captured world titles in three weight classes, including holding all four belts to become an undisputed champion at super-lightweight in 2017, highlighting his prowess in the sport.

The 31-year-old American is the firm 1/20 favourite to pick up the win, which doesn’t offer much value, but the price of 7/4 to win by KO looks very tempting.

Khan, who is the big outsider to win at 8/1, is looking forward to the contest and wants to prove to everyone that he deserves to be fighting at the top level.

“A win here would top everything,” he said. “Now I’m reaching for something no-one really expected me to reach. I’d watch fight previews from here over and over. I’m living that now. I want to win this so badly now just to prove a point.”

The fight will need to go the distance if Khan, who could decide to hang up his gloves if he suffers defeat, is to pick up a shock victory and it is 11/4 for this to happen.
