The US have never won on Costa Rican soil.
"I think there is a sense - one because of where we are in the standing and two because of the form that we've been on - that it's not cocky but it's very confident that we're going to do well on Friday and that it's going to look different than any other qualifier has ever looked here for the US," said Donovan.
"I think we go into it with that attitude. If it doesn't work out, it doesn't work out. But we're going to go in with the mentality and the attitude that we want to win this game."
