The Brazil captain has scored in his last two La Liga appearances for the Catalan giants, including a penalty in Saturday's 6-0 win over Sporting Gijon.
The 24-year-old has been criticised for an overall drop in form, however, with the attacker struggling to meet the standards that he set earlier in the season.
Enrique has admitted that Neymar is currently 'not at his best', but has backed the former Santos attacker to hit top form in the final weeks of the season.
"Neymar isn't at his best, but he never hides. That alone can make you a top player. He must continue trying to regain his imbalance, even if he doesn't score [in that time]," Enrique told reporters.
"The fans chanted his name several times to encourage him, and I hope it stays that way. I'm optimistic because I've seen my players reverse a very complicated situation."
Neymar has scored 29 times in 45 appearances for Barcelona this season.
