Bussell said that the BBC Breakfast presenter is now capable of pulling off technical dance moves, but argued that he needs a confidence boost if he is going to win the show.
"I think now he has the ability to do the steps and Ola [Jordan] just has to give them to him," the ballet star told It Takes Two. "He shouldn't be scared of it. He always says, 'I'm good at this, but I'm at bad at that'. He has to believe in himself!"
Alesha Dixon backed up her fellow judge, commenting: "I felt on Saturday that he was dancing from the heart.... I felt something when he danced that waltz, it was very romantic."
Bruno Tonioli added: "Technically, he is not the strongest dancer. But when he comes out people love him - I love him. It is like watching your mate who had made it."
Hollins will compete against Ali Bastian and Ricky Whittle in Saturday's Strictly semi-final, which airs at 6.45pm on BBC One.
