Bayern Munich coach Thomas Tuchel admits they're rank outsiders facing Manchester City on Wednesday night.
Bayern host the second-leg of their Champions League quarterfinal trailing 3-0 on aggregate.
Tuchel said: It will be a miracle if we pull it off, but we can't just talk a miracle into existence.
"Playing against Manchester City is a massive challenge, they are in great form recently. It's in our own hands, we need to give it everything.
"We're not alone, we have a good team and we have the fans. We have to go step by step.
"We need the momentum and those little moments to go our way - it won't come off otherwise. We have to get the balance right. We know the size of the task that awaits us and just how difficult it will be."
He added: "We believe in ourselves and know we can win both halve.
"If we do that, anything can happen, especially if we get a bit of luck which we didn't have in the first leg. We will take things one half at a time."
