X Factor judge Cheryl Cole has admitted that the contestant she is most concerned about at the minute, is Olly Murs.

Cheryl claims that Olly hasn’t shown his full potential to date, but hopes his legions of loyal fans will keep him safe from elimination.

She told the Kiss 100 Breakfast Show: “I’m worried about Olly. Olly is kind of not happening at the moment, but one to watch out for. He’s a dark horse and all the girls love him.”
