Interim Chelsea manager Roberto Di Matteo has said that his side need passion and luck to advance to the quarter-finals of the Champions League.
The Blues face Napoli in the second leg of their last-16 tie tomorrow and must turn around a 3-1 deficit from the first leg to advance.
Di Matteo said: "We need a great performance tomorrow night, but a little bit of luck as well.
"We need to deserve that bit of luck to go through in a cup competition.
"We want to show a passionate performance to try and turn this tie around."
Di Matteo has won both of his opening games since taking over following Andre Villas-Boas's dismissal.
