Ezequiel Lavezzi scored either side of half-time and the prolific Edinson Cavani also netted to put the Serie A outfit in control after Juan Mata had put the Blues ahead in the first leg in Naples.
Roberto Di Matteo has taken control of first-team affairs at Stamford Bridge following André Villas-Boas’s sacking – and the Italian has guided the Blues to successive victories over Birmingham City in the FA Cup and a 1-0 win against Stoke City on Saturday.
And Drogba is confident Chelsea can reach the quarter-finals – as long as they can replicate their recent performances on Wednesday night.
“I think it’s possible [to overturn the 3-1 deficit]. If we play the way we did on Saturday and against Birmingham City, it will be tough, but possible,” said Drogba.
The Ivory Coast striker’s team-mate Branislav Ivanovic insisted Chelsea will approach the game as if it were a cup final, and believes the Londoners’ team spirit makes progressing past Napoli an achievable goal.
“We will give everything against Napoli. For us the game will be like a final where we have to play at our very best,” added Ivanovic.
“We’re 3-1 down but with the spirit of the players at the moment, it is possible.”
