Didier Drogba scored the only goal in the first half of the game.
“We created enough chances to score more but it’s very important we keep a clean sheet at home,” Lampard told Sky Sports.
“Juve are a top team. We’re past the group stages now and any team you play are going to cause you problems.
“But it’s good we didn’t concede and we have the chance to go there and cause them some problems.
“It wasn’t the best performance over the 90 minutes but it was a big performance and a big result.
“There were patches where we played well. We started very well but at times we maybe sat off a little bit.”
