Lampard feels the tie is in the balance but was happy Chelsea restored some pride for Premier League clubs in Europe having become the first out of the six still competing in the Champions League and Europa League to score in the knock-out stages.
He said: "We can't do anything about what other English teams do but in any competition we want to do our best. It's the way we play. The second leg will be tough. People will probably say this was a good result for us but knowing the firepower they've got, particularly in Didier Drogba, then we can't take anything for granted."
Lampard and Drogba shared many successes at Chelsea before the latter left the club in 2012 after their Champions League triumph.
"It was an honour to play against him and an honour to play with him for so many years," added Lampard to the London Evening Standard. "But we know if you switch off he will score so we'll have to watch him back at the Bridge."
