The five-time champions will face minnows Costa Rica in St. Petersburg on Friday after drawing 1-1 with Switzerland on Sunday. Costa Rica were beaten by Serbia 1-0 in their opening game.

"It's going to be a very difficult match given the loss in the first match and then now for us it was a draw. I think there's pressure on both sides and it's more than normal. We're used to that kind of situations. The team is fully aware of what we are going to be facing tomorrow," Silva told journalists.
