The head coach of Team GB men's curling team, Soren Gran, has criticised the Canadian players' aggressive approach to the sport.
The two sides will clash in the final of the event at the 2014 Winter Olympics in Sochi on Friday.
"The aggressive style we have seen from the Canadians here, that's something I don't like about the sport," the Toronto Sun quotes the Swede as saying.
"I don't think it helps anyone. It doesn't help the player and it doesn't help his teammates. I tell my guys to work a different way. If they miss a shot they've got another 15 to play, you can't be angry with the one you miss.
"If I see the team we are playing against get aggressive and show anger, I think our guys should be happy because we'd have them exactly where we want them to be. I don't think that helps."
Gran has been part of the British coaching staff since 2011.
