George Sampson has reportedly claimed that Simon Cowell is to blame for the disappointing performance of his debut single.

The Britain's Got Talent winner peaked at number thirty in the chart when he released 'Get Up On The Dancefloor / Headz Up' last month.

Sampson has since brought out a DVD entitled Access 2 All Areas, which includes behind the scenes footage of his recent UK tour and a dance tutorial.

Discussing how Cowell's decisions led to poor single sales, Sampson told the Daily Star: "It was purely based on the timing, which was wrong. We should have done the DVD first to get the visual and let everyone see the new routine on the Royal Variety Show, then brought out the single."

The 15-year-old also apparently suggested that Cowell had mishandled the career of Leon Jackson, who released his debut album Right Now in October after winning X Factor's 2007 series.

"He left it too long," Sampson explained. "People forget about you after a year, he needed to move quicker."

Yep, because some 15 year old who can't dance and shouldn't have won knows how to run a music business successfully ...
