While Argentina are the favourites to go through to the quarter-finals, Xhaka is confident that he and his teammates can cause an upset.
"Argentina are indeed favourites, but that also means that we've got nothing left to lose now," he is quoted as saying by Shoot.co.uk.
"We will do all we can to survive against Argentina. It's only one match and everything is possible!"
Switzerland have reached the quarter-finals of the World Cup on three previous occasions.
