Tottenham boss Harry Redknapp has told his players to leave everything on the pitch at Real Madrid.
Spurs take on Jose Mourinho's nine-time winners at the Bernabeu - and Redknapp has told his players to enjoy the special occasion.
However, he has warned them if they do not deliver a good performance, it would be a massive let down to him.
He said: "Matches like this one don't come round very often so we should make the most of it."
In a shock on Saturday, Real lost 1-0 at home to Sporting Gijon - making it Mourinho's first home defeat since 2002.
