The makers of the US version of The Voice have announced a new twist for the show's battle rounds.

TVGuide.com reports that executive producer Mark Burnett has revealed that in the upcoming battle rounds the coaches - Christina Aguilera, Adam Levine, Blake Shelton and Cee-Lo Green - will be able to poach contestants that a rival coach has decided to send home.

If more than one coach wants the singer in question, the performer will be able to decide which mentor they want to work with, as in the show's blind auditions stage.

Each coach will be allowed to save two contestants and will finish the battle rounds with 10 singers, but in a new, two-week "knockout round" each coach will then cut their team to five.

"We all just wondered, what is it that we can do during the battles to keep the competitive element going," said Burnett. "And this came out of a collective talking. Last weekend we taped it, and it was very exciting."

The show returns to American television on Monday September 10.
