14-year-old Liam McNally has been tipped as a contender to win 2010's Britain's Got Talent after impressing the judges with his spine-tingling rendition of Danny Boy.

While the schoolboy was put through to the next round, Simon Cowell admitted he was concerned his outstanding voice could break at any moment and told him to make the most of this opportunity while he could.

The unassuming teen admitted he had no experience performing in front of such large crowds and usually just sang in his bedroom.

After his performance, Cowell added some drama by keeping the boy in suspense about what he thought. He said: 'I wouldn't call you a good singer... I would call you a fantastic singer. What you've got, when you sing, you have fire in your eyes, you have emotion. You have a real warmth."

"The problem is what you have, you're gonna have for six to nine months and it's gonna go."

Piers Morgan than tipped McNally as a possible finalist, saying: "You're a serious contender to win Britain's Got Talent."

Speaking ahead of his audition, McNally said: "I've always wanted to sing on the Royal Variety Performance. When my Mum and Dad tell me I'm a good singer it's good, but if the judges were to say it, it would make me believe my dream."

Liam wants to pay his mum's debts because she's "always moaning about her mortgage."
