Ricardo Carvalho admits Chelsea must learn from their mistakes against Bolton if they are finish the job against Liverpool.
Chelsea lead the Reds 3-1 after their superb performance at Anfield but the way they conceded three goals in nine minutes against Bolton would have given much inspiration to Rafael Benitez and his Liverpool squad.
Liverpool have to score at least three goals if they are to have any chance of turning the tie in their favour but Carvalho is convinced the Bolton debacle provided them with the timely wake-up call they needed.
"We have to learn from those mistakes and it is good to play three days after that game," said Carvalho. "We conceded too many when normally we are strong in our back four."
Chelsea will be without suspended centre-back John Terry but Carvalho is adamant they can compensate for the England captain's absence.
"We will miss John but we can't change the rules, he got suspended so we have to try our best," he added. "The back four has to be compact and play as normal."
The Portugal international insists Liverpool should not be taken lightly despite the two-goal cushion.
"We have to be aware, this competition means a lot for us so we want to go through," said Carvalho.
"We have to think first of ourselves and after look for them, but if you are in good shape you can win the game and go through.
"We are improving always, we had some problems in the previous months but I think you become stronger and now we are in good shape to win a competition for the club.
"I won in 2004 [with Porto] but lost last year, but to win the trophy you have to be there in the final."
Trailing 3-1 from the first leg, and yet to beat an English club away from home in Europe, much will depend on whether Liverpool's midfield talisman Steven Gerrard shakes off a groin problem to play.
But even though the Reds have not scored three goals at Stamford Bridge in two decades, Benitez would have taken heart from Bolton's performance.
But it was also the perfect wake-up call for Guus Hiddink and his squad, and the Dutch coach is determined they will not sit back and defend their lead.
"It cannot be a cautious game where you have a kind of balance in a game where nothing happens for an hour, then maybe a team takes some risks at the end," said Hiddink.
"That's not in both teams' souls. We have to go for the win at home.
"Going 4-0 up against Bolton and then conceding as we did, was like an alarm clock ringing for this up-coming game.
"We should have controlled the last part of the game. We can concede one, at 4-1, but one alarm bell is enough.
"We've prepared very seriously. A lot of people have said, if you win an away game in Europe like we did, then you won't have any concerns for the second game.
"But we're not thinking like that. Liverpool are a very good team who play beautiful football, and we're very aware of that.
"There is no such reason, whatever the team you are playing against but especially Liverpool with what they did in the past, to have complacency."
