Amir Khan has told Michael Jackson that he is welcome at Freddie Roach's gym any time if he wants to see how to prepare for a fight properly.
Khan was responding to remarks made by Jackson who stated that he has had to postpone his opening dates at the O2 because of a lack of time to rehearse due to other shows taking place there.
The 21-year-old, who will fight for his first world title against WBA light-welterweight champion Andriy Kotelnik at the O2 on June 27, insists Jackson cannot hide behind his fight as an excuse for letting his own fans down.
"My business is all about preparation too and I'm over here working much, much harder than Michael is and I'm certainly not postponing my fight," Khan revealed.
"Tell my fans that I am prepared and am ready to put on a show far more spectacular than his anyway!"
The Bolton boxer added: "Ive always been a big fan of Michael Jackson but I was annoyed to read his comments on the internet.
"I'm annoyed that he has used my fight as the reason for letting his fans down and now it's up to me to light up the O2 myself on June 27 with my own version of Thriller!
"In common with Michael Jackson my night will also end with my glove raised up high too but that's where the similarity will end, I'll be crowned champion of the world.
"Tell Michael if he wants to come to Freddie Roach's gym, I'll show him what it takes to prepare and to rehearse properly. Then he'll really have something to have a song and dance about."
