Leeds manager David O'Leary has revealed the fear of failure is the driving force behind his side's hunger to avoid being a shock UEFA Cup first-round scalp.

The English Premiership leaders face the prospect of an early exit to European minnows Maritimo tonight just five months after reaching the semi-finals of the Champions League.

They lost the first leg 1-0 at the Estadio dos Barreiros on the holiday island of Madeira.

O'Leary's players were accused of taking the game lightly in the wake of their European eploits over the last two seasons, the club also having reached the last four of the UEFA Cup in 2000.

"The lads know they let themselves down last week," said O'Leary. "But they're only human beings, although human beings can play just as badly twice.

"But they were no mugs. It wasn't just a case of us turning up because they set out to play a certain way and it worked, while we just didn't play.

"I hope in the back of their mind they're thinking just how much they will miss playing in Europe if they do go out after enjoying two years full of great adventures. It's going to be a tough, frustrating game - but it's a must-win game."
