LIVERPOOL, England -- Nobody knows better than Liverpool that a three-goal lead is not always a guarantee of success in the Champions League.

They will never forget the "Miracle of Istanbul" at Anfield -- that night in May 2005 when Rafael Benitez's team overturned a 3-0 half-time deficit against AC Milan to win the club's fifth European Cup on penalties -- but there have been more recent reminders that such an advantage is not enough to be certain at the highest level of European competition.

Back in November, Jurgen Klopp's team surrendered a 3-0 lead against Sevilla in Spain to emerge with a draw in Group E and there was, of course, Roma's remarkable 3-0 victory against Barcelona at the Stadio Olimpico earlier this month, which saw the Italians eliminate the Liga leaders, despite suffering a 4-1 first-leg defeat at the Nou Camp.

So Klopp's men will certainly not travel to the Italian capital next week with any thoughts of their job being done as they attempt to defend a 5-2 lead in order to book a place in the Champions League final, on May 26 in Kiev.

"There would have been work for us to do when we win 5-0 because Roma would have tried everything to strike back anyway, so that's not a big difference.," said Klopp. "What I learn tonight is that we can win the second game as well, even when it will be different. Roma needs to score goals against us."

Liverpool have seen both sides of the coin when it comes to a three-goal lead, while Roma will go into pitch next Wednesday believing they can repeat the heroics of their Barca fightback. The Stadio Olimpico will be infused with belief and hope after seeing Lionel Messi and co. dumped out in sensational fashion.

But while Liverpool only have themselves to blame for allowing a five-goal lead to be cut to three as a result of Edin Dzeko's late strike and Diego Perotti's penalty -- Klopp said "the Liverpool way is always a little bit harder" -- they can take comfort in the fact that they have more goals in them than any other team in Europe.

That firepower should be enough to get them through next week's test and will also give them confidence that they can defeat either Real Madrid or Bayern Munich in Ukraine to take the European Cup to Anfield for a sixth time.
