The judge said this year's hopefuls lack the necessary "personality" to achieve success.
He insisted that the singers are playing it too safe and failing to choose tracks which showcase their talents.
He also said the remaining six contestants should be less guarded when answering questions, as their comments so far have not revealed their true personalities.
He said: "They are giving very safe answers to questions, making safe song selections. We are not getting a sense of who they are. We have to try to pull it out of them more.
"You cannot deliver an uninspired performance at the top of the show. And you can't be up there imitating another singer."
