Basketball legend Shaquille O'Neal has taken aim at David Beckham after the soccer star declined his offer to compete on his new reality TV show.

O'Neal has been desperate to land a battle with Beckham on his "Shaq Vs" program, which will see him take on his rival sporting peers at their own game.

He has already set up a swimming battle against Olympic athlete Michael Phelps, a boxing bout against former world champion Oscar De La Hoya and a tennis game against Serena Williams.

Last month, O'Neal taunted the soccer star in a series of posts on his Twitter.com page: "Dear David Beckham. I know you have heard about my Shaq Vs show, anyway u will never score a goal on me. I challenge you, lil' man. David Beckham, I know you hear me. Don't be scared, don't make me call u out. Don't make me Tweet to two million people that yur (sic) scared of Shaq."

And the athlete has continued his tirade after learning Beckham rejected the offer, adding: "Official, today is David Beckham is scared of Shaq day, he should b scared, he can never score a goal on me."
