Judges Cheryl Cole, Simon Cowell and Louis Walsh and presenters Dermot O'Leary and Holly Willoughby all backed the Essex singer to triumph when asked to write down their predictions at Boot Camp earlier this year.
Dannii Minogue was the only judge not to back Murs, predicting that Nicole Jackson would win. However, Minogue was forced to send home Jackson at the Judges' Houses stage.
"I was way off - she was in my top six. But she completely messed up at Judges' Houses," said Minogue. The Xtra Factor host Willoughby and Walsh both suggested that Jackson apply for the show again next year.
None of the judges picked Joe McElderry, who was crowned the 2009 series winner last night.
