Barcelona coach Ernesto Valverde says they must improve their goalscoring form going to Chelsea on Tuesday night.
Barca travel to Chelsea for the first-leg of their Champions League round of 16 clash.
While the Catalan side are well-known for their free flowing football they have struggled for goals away from home.
"These are the statistics that we have and it gives an idea of how difficult the competition is," Valverde told a press conference.
"It is not just the case this season but before as well, and it is the case for us and for others. But while it has been like this so far it doesn't mean it will be the same tomorrow. We are looking to change this run and we will try to score while at the same time aware of how strong the rival is.
"They are a physical team that defends well and can cause problems on the counter-attack. Tomorrow is another game and we will do what we can to go through."
Surprisingly Lionel Messi, for all his goal scoring feats in his career, has never scored against Chelsea.
"I am not sure if past facts count for anything but I know that it is an important tie for everyone, for Messi, for me and everyone at Barcelona," continued Valverde.
"It will be difficult for the rival we face but it is an important game as we want to continue going. Possibly Leo has not had luck against Chelsea but that is all in the past."
