The Uruguay international striker has failed to find the net in the last three matches.
"Luis Suarez is a winner and he likes to win every game," said Enrique.
"Of course he was really disappointed for the misses he had on Thursday but he is a key player and one of the best strikers in the world.
"Like everyone he is still a person who makes mistakes and Thursday was not his day. But all the chances he has he makes all on his own."
