"We had the players to get a result last week, we just didn't employ our team plan as well as we should have, which makes it an uphill battle on Wednesday," he said.
"It wasn't the best result to come back with but we know there's a full stadium to play in front of and we're just buzzing to do that.
"There's still 90 minutes of football to go and football's a strange game. Stranger things have happened than us winning 4-0 on Wednesday night."
Mexico trained in Wellington for the first time on Sunday, looking focused and energetic. Winger Miguel Layun said Mexico would not rest on its comfortable lead.
"The result (in Mexico) doesn't mean anything to us," he said. "We know we had a great game and we got a comfortable result. But we want to win here and it isn't going to be easy for us.
"We want to attack, we want to do the things we do better and attack is one of those so we're going to keep that mentality."
