More from Amir Khan: "Floyd Mayweather is the ideal fight for me. I think he is the best pound-for-pound boxer and it would be a game of chess, but against Mayweather I would be too skilful. I have the skill and movement to beat him.

"I feel better now than I did when I was 25. I'm dedicated to the sport and I know there's a few years left in me. I'm going to try and force that fight with Floyd Mayweather. He will not be able to hurt me. He does not have the skill for me."

Former undisputed heavyweight world champion Lennox Lewis ‏on Twitter:, external I would love to see Mayweather v Khan or Mayweather v Pacquiao in May. Best case scenario: Mayweather v Khan in May and if FM wins then Mayweather v Pacquiao in September as Grand Finale.

Beaten fighter Devon Alexander says: "I don't want to make any excuses. He was the better man and I wasn't good enough tonight. I was supposed to follow the game plan, but this is a loss and no one wants to lose."

Asked if he deserves a fight with Floyd Mayweather, Amir Khan replies: "I really believe I've earned my shot against the best boxer in the world and that's Floyd Mayweather. We will come back here and take the belt. I want my chance."

A very happy Amir Khan says: "I trained very hard for this fight. I knew I had to make a statement tonight. It was against a tough, very skilful guy, but it was one of my best performances.

"I'm the best boxer and have the quickest hands in the world. I've just turned 28 and I'm getting better and getting quicker, I just had to become smarter.

"It's in my blood to fight, but today I was able to reset myself. I've got the best jab in the business."

Scores of 119-109, 118-110, 120-108. One judge says Khan won all 12 rounds in Las Vegas. The other two judges give him the victory by 10 and eight-round margins.

Alexander should be throwing everything at Amir Khan in the last, but instead tries to pick him off with single punches and it is a strange tactic for a man surely miles behind on the scorecards.

At no stage is Khan in trouble in the last, but a durable Alexander, despite taking some punishment, hears the final bell and deserves a lot of credit for that. We go to the judges' scorecards.

"Why you letting him do what he wants to do?" asks a pretty unsupportive Alexander corner.

He is trying, but quite simply he has not been good enough. Alexander is not having much success with the jab and Khan, faster and more intelligent, just has to avoid a knockout in the last to win this one.

Promoter Eddie Hearn, who wants Khan to fight Kell Brook next, writes on Twitter:, external Amir has blistering hand speed and is always wide open in exchanges - always great to watch.

Is it enough to get him a fight with Floyd Mayweather? Maybe? Maybe not. But Khan has produced a highly professional performance. Devon Alexander needs one magic punch. If it goes the distance than the Briton's arm will be the one raised.

More from Khan's trainer Virgil Hunter: "He is having to come forward, but he's not effective when he does so."

Devon Alexander's corner know their man has to do something special to win this. 'You have to turn this around' is the bit we can write from his corner after the ninth. Some quotes, we couldn't repeat.

Not the most eventful round of an entertaining contest, with Alexander reduced to huge, speculative rights looking for a knockout punch.

Full credit to the American, who may well have just got his first round on the board. He lands three right hooks with his best work of the contest, and also has success with the left.

The camera focuses on Amir Khan's dad, Shah Khan, who looks a bit worried. His son is still well ahead on points, but this round is a warning that the job is not finished just yet.

It is a masterclass from Khan so far, surely one of the best performances of his career to date, in this his 33rd professional fight.

Khan is landing more, although Alexander tries to make a dent with some body punches. But it is another round for Khan. He looks relaxed, and in total control.

The best British pound-for-pound boxer over the last 20 years?

Shaun McAllister: It's got to be Joe Calzaghe. And if he was to make a comeback he would still beat Carl Froch on points. He is still young enough to make this British fight of all fights. PS I love Carl the Lion Heart my second best hard and nails fighter in the last 20 years.

Stefan Domingo Lanigan-Macedo: For the 10-minute walk in against Kevin Kelly in his first fight in America, predicting to his face in the weigh in he would knock him out in the fourth and then knocking him out in the fourth. Prince Naseem will always be my favourite.

A lovely left hook from Khan, quicker to the punch, rocks Alexander but the Brit can't capitalise against a durable opponent, who is taking a fair bit of punishment.

With 40 seconds of the round a left-right Khan combination also finds the face of the American. He is well behind on the scorecards, but still in there.

The closest round of the contest so far, but did Alexander do enough to win it. I'm not sure. Khan is trying to avoid getting into a brawl and goes defensive as Alexander produces some of his best punches.

"You're beating him up, he won't be able to take this for a few more rounds," screams Khan's trainer Virgil Hunter.

It is entertaining so far. But Khan is proving too good. However, it is an exciting contest, with a huge hook from Khan drawing gasps from the packed crowd at the MGM Grand.

All going to plan for the Englishman so far.
