Goalkeeper Petr Cech claims the disappointment of twice missing out on the Champions League final will drive Chelsea on to glory in tonight's showdown against Liverpool.
Chelsea grabbed a vital injury-time away goal in the first leg of their semi-final at Anfield last week when defender John Arne Riise headed into his own net.
The tie remains level at 1-1 but Cech believes Riise's blunder and the heartache of two previous defeats at the hands of Liverpool will spur the Blues on.
The Czech said: 'We all remember the moment we lost the semi-finals, which is something we don't want to repeat.
'This could be something that drives us on. We don't want that again. Everyone knows what we are playing for. You don't need to speak, you need to play.
'The away goal is very important and it completely changed the scenario of this semi-final.
'It was really important at that moment, but we need to prove that it was a big moment for us. If we concede a goal, this advantage will be gone.
'I hope we have the strength. We showed many times in the league, or in the cups, that we do. We had the luck with the own goal, we hope it's going to be decisive.
'I think we were ready to go to the final on the last two occasions. We wanted to do our best, but it didn't happen.
'This is a third opportunity, the fourth for the club, to make it happen. We don't want to miss this opportunity, we want to be in the final.'
Chelsea striker Didier Drogba has been criticised by Liverpool boss Rafael Benitez for going to ground 'too easily' this week but Cech does not think such remarks will affect the Ivorian.
'There is always a lot of words said before the big games,' said Cech. 'But the main point is how we're going to play on the field.
'Since Didier arrived in England, people have been saying every week he's a diver. But he's been playing really well, has an amazing record in scoring goals. It's not going to disturb him in any way.'
Cech insists Chelsea are well prepared if the tie goes to another penalty shootout.
'You never speak about it, but every player and team studies it for penalty shootouts,' said Cech.
'But, in the end, you have people who miss. It's about dealing with the pressure to take the ball and put it in the back of the net.
'It's always about the players and how they deal about the pressure in the moment. It's not easy after 120 minutes when you're tired and have to score. Not everyone can deal with that.
'But in the penalty shootouts, there's always someone who misses. I hope that, this time, it won't be us.'
