Tottenham Hotspur manager Harry Redknapp and winger Gareth Bale are confident Spurs can pull off the greatest of comebacks against Real Madrid and qualify for the semi-final of the Champions League.
The north-Londoners have a four-goal deficit to make up after a thrashing at the hands of Jose Mourinho's side in the Bernabeu a week ago.
But Redknapp insists his side must believe.
"We know it would take a miracle but miracles can happen," said Redknapp.
"If we play very well you never know.
"I'd take penalties, we have been practising."
"Everyone says we have to attack them but you are playing against world-class players, so you don't want to keep bombing everyone forward and getting ripped open on the counter-attack.
"So long as we play well and give it everything we have I can't ask for anything more.
"We have to see if we can win the game and see how the game develops."
A was the case in Spain, when Tottenham went down to 10-men, Bale will be of vital importance to Spurs in the second leg.
His startling performances against Inter Milan in both group games has been the highlight of Spurs run in the Champions League, and the Welshman isn't ready for their campaign to run just yet.
"Hopefully we can produce the miracle. Madrid lost 4-0 at Anfield not long ago. Why can't we do it at White Hart Lane?
"We are going to try and we're not going to give up. It's an almost impossible challenge but we're going to see what happens. We need to be optimistic."
