He said: "We began quite loose, without aggression. Chelsea had several clear chances, but little by little we have grown in confidence, we had a pair of chances to score... The important thing was not to lose and to follow the instructions of the trainer (Ronald Koeman).
"We know that we must work hard to score goals. The team does not have confidence, but we're trying to again find a way to score. We have had a series of important injuries, but this is the same every year.
"We must look forward and work with what we have."
