Defender Ricardo Carvalho admits Chelsea's mistakes against Bolton Wanderers at the weekend will serve as a timely reminder to stay fully focused against Liverpool in the Champions League on Tuesday night.
The Blues shipped three goals in eight second-half minutes at Stamford Bridge against the Trotters, winning the game 4-3, and Liverpool must also score at least three goals if they are to overturn a 3-1 deficit from the quarter-final first leg.
But Carvalho - who will line up alongside Alex in the heart of the Chelsea defence in the absence of suspended captain John Terry - insists there will not be a repeat of the Bolton collapse on Tuesday.
"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."
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."
Five great European comebacks
• Deportivo La Coruna 4-0 AC Milan 0 (Deportivo won 5-4 on aggregate, champions League quarter-final, April 2004)
Deportivo left the San Siro after the first leg on the end of a 4-1 defeat facing the task of overhauling a three-goal deficit against an Italian defence including Paolo Maldini and Alessandro Nesta. Walter Pandiani's early goal was added to by Juan Carlos Valeron's header half an hour later as the Spanish side started to believe. Just two minutes before half-time Albert Luque held off Nesta before smashing the ball into the roof of the net to put the home side ahead on aggregate. Veteran substitute Fran stunned the Rossoneri when he sealed the amazing comeback with a fourth goal 15 minutes from time.
• Man Utd 2-1 Bayern Munich (European Cup final, Barcelona, May 1999)
United trailed for nearly the entire game after falling behind to Mario Basler's sixth-minute free-kick. But, in the most amazing finish in the history of European Cup finals, United turned the game on its head. Substitute Teddy Sheringham equalised with a shot on the turn from eight yards and extra-time beckoned. But United had other ideas and, when David Beckham's corner was flicked on by Sheringham, fellow substitute Ole Gunnar Solskjaer rifled the ball into the roof of the net to spark joyous scenes among United's near-40,000 fans in the Nou Camp. United had become the first club to win the treble of European Cup, Premier League title and FA Cup.
• Liverpool 3-3 AC Milan (Liverpool won 3-2 on penalties, Champions League final, Istanbul, May 2005)
Liverpool beat Milan in a penalty shoot-out to win the Champions League after sensationally coming from three goals down at half-time. Paolo Maldini gave Milan a first-minute lead, and two goals from Hernan Crespo put them in a seemingly unassailable position at the interval. Reds captain Steven Gerrard gave Liverpool hope, and Vladimir Smicer and Xabi Alonso levelled in a seven-minute spell. Jerzy Dudek then saved from Andrea Pirlo and Andriy Shevchenko in the shoot-out to clinch a stunning victory.
• Juventus 2-3 Man United (Utd won 4-3 on aggregate, Champions League semi-final, 1999)
After a 1-1 draw at Old Trafford, going 2-0 down in the opening 10 minutes of the second leg at the Stadio Delle Alpi was not what the Red Devils had planned. Captain Roy Keane hauled his side back into the game, heading home from a corner before getting a booking which was to rule him out of the final. Keane pushed his team forward and Dwight Yorke levelled the scores with a diving header from Andy Cole's cross. Cole then netted United's third as they reached their first European Cup final in 31 years.
• Basle 3-3 Liverpool (Champions League group match, November 2002)
Liverpool trailed 3-0 in Switzerland as Julio Rossi, Christian Gimenez and Timothee Atouba all found the net in the opening half an hour. Danny Murphy's shot from the edge of the area restored some pride before Milan Baros set up Smicer for a sliding close-range finish three minutes later. Michael Owen got Liverpool level with seven minutes remaining, when he scored the rebound from his penalty. However, despite the comeback Liverpool still crashed out of the competition in the group stage.
