"It's the truth we are the underdogs, we know that. We respect Chelsea but, at the same time, we know that we can beat them," said Reina.
"We must score at their stadium if we are to go through, and if we were to score first then it would put a lot of pressure on them and then it would be a good situation for us.
"We are confident we can get to the final - that is my message to our supporters."
