"Just because they are the world champions doesn’t mean that we have to think it impossible for us to win the cup. We have to give credit to Brazil’s national team.
“We have to put Brazil’s national side where it deserves to be. This trophy is important for us and will help us move up the world ranking.
"We’re on the right track and God willing, we’ll win it."
