The Croatia international has not scored for the club since 9 December, missing out again in the 2-1 home defeat to Norwich on Saturday.
But Naismith believes his team-mate is due some luck in front of goal as they look to secure a Europa League berth next season.
"There's no doubt he can handle the pressure," Naismith told the Liverpool Echo.
"If you look at how the games are going now the ball just isn't breaking to him. It's not about him not trying or being lazy.
"There were a couple of times against Norwich again when the ball didn't fall to him. But his other parts of his games are working well.
"He put a few balls across the face of goal for other people, and he'll always give you that if not the goals he usually scores as well.
"You could look at it that way, but the goal came from Ossie (Leon Osman) bursting a gut to get into the space which Jela had created. That was where the goal came from.
"That's one thing about this club - it's never about one individual, it's about the team. If the ball isn't dropping to Jela he'll become the creator which is what the manager would expect."
