His comments are unlikely to go down well with Len, who recently insisted he wouldn't leave the dance competition by choice.
"Sometimes I read, 'Goodman isn't going to do it any more.' That's a load of nonsense," the 70-year-old told the Telegraph. "I'll never not do it. I'd never not do Strictly, it's fantastic. I love it."

Craig also said that he thought Strictly has taken the departure of Sir Bruce Forsyth in its stride.
"People always ask me if we're missing Brucie and the answer is of course. But Strictly is a supple beast and always moves with the times," he said. "And Claudia's fab, she gets wackier each week."
