The Merseysiders have failed to win in their last five games in all competitions, including two defeats in their previous two outings.
"I think we are doing well," Enrique is quoted as saying by Eurosport. "The problem is, in the last three games we have been trying to score goals and had chances to score and then we have had mistakes.
"We have to improve in defence and in attack do what we are doing and hopefully we will have better luck."
