Watch ‘The Voice”s Rob Cole and Marty O’Reilly in the Knockouts (Exclusive)

Michael Bublé has a tough decision to make.

In a clip shared exclusively with PEOPLE from the Monday, Nov. 10 episode of The Voice, Rob Cole and Marty O’Reilly went head-to-head in the Knockouts — and the Canadian crooner was left to decide who to send home.

For their respective performances, Cole performed “Wondering Why” and O’Reilly performed “The Letter.”

“I’ll be damned! I’m gonna start with Marty. Man, the way you sing, the way you howl and growl, that ain’t nothing but the dog in you. I love that. You could win The Voice. You were that good,” coach Snoop Dogg, 53, said.

“Brother Rob Cole, the way you started on that piano and then you stood up and went to a whole other level like, that’s super star. But to me, I’d go with the dog,” he added.

Coach Niall Horan complimented Cole’s piano skills and told him he “told the story so well.” Meanwhile, for O’Reilly, he said his performance was “so captivating to watch.”

“I don’t even know where you go here,” the “Slow Hands” singer, 32, said. “Both of these still deserve to be here and it’s sad but someone actually has to leave here right now.”

Coach Reba McEntire told both contestants they did a “great job” — and she too loved Cole’s piano playing.

“I loved you singing a Joe Cocker song. You channeled a little bit of Joe here tonight. Fantastic,” the “Fancy” singer, 70, told O’Reilly.

When it was the “Home” singer’s turn to speak, he said that both of his contestants “executed perfectly.”

“Oh my God, I should not have put you two together because both of you are too good not to go on,” he said. “The winner of this knockout is…”
