Danny O'Donoghue has admitted that The Voice UK needs to find a hit winner.
In three series the show has so far failed to launch a successful career for its champions, with the latest - Jermain Jackman - reaching only Number 75 in the charts.
"I think it is a little worrying the show hasn’t found a star yet," Danny said.
Speaking to the Daily Star on Sunday newspaper, he explained:: “If it doesn’t have a hit next year then it will just become a TV show rather than a music platform and that would be sad.
"I’d say it would have two years to run if it doesn’t produce a hit artist.”
And Danny told the tabloid that he wouldn't want to return to the panel, which is in need of at least one new coach after Kylie Minogue left after just the one series.
He said: "No. I don’t think I would go back.
"I love the show and am still a massive fan.
“But I want to be remembered for being Danny from The Script not Danny from The Voice.”
While the show's winners haven't done well, some acts from the series have had a taste of success.
Series one contestant Becky Hill, who didn't even make the final, has had two top ten hits including the show's first ever Number 1 earlier this year.
The Voice UK will return in 2015 on BBC One.
