Jose Mourinho is confident Chelsea can overcome playing the first leg of their UEFA Champions League quarter-final at home.
The Blues were drawn against Valencia in the last eight of the competition, but the Spanish side have the all-important home advantage in the second leg.
Chelsea welcome Valencia to Stamford Bridge on Wednesday before the return leg at the Mestalla six days later.
Mourinho is optimistic on his side's chances having prevailed over Bayern Munich two seasons ago in a similar situation.
"It is a great but difficult opportunity to go through to the semi-final stage for the second time in three years," Mourinho said.
"We showed against Bayern Munich two years ago how to win a quarter-final at home in the first leg and we will need to play that well again to progress."
Chelsea won the first leg against the Germans 4-2, before holding on to advance to the semi-finals with a 3-2 defeat in the second leg.
Meanwhile, Chelsea goalkeeper Petr Cech has the same outlook as the Portuguese tactician.
"It would have been better to play the second leg at home but we have to forget about that now and concentrate on our own game," Cech said.
Cech hopes to meet up with former team-mate Asier Del Horno, but does not know if the Valencia left-back will be involved because of an Achilles problem.
He added: "I don't know if he will be ready to play after his injury problems but it will be nice to see him again."
