The Barcelona boss has challenged the Brazilian to improve his strike rate in the absence of Lionel Messi but has is delighted with his all-round contribution
The Brazilian has managed just five goals in 20 competitive appearances for the Blaugrana since his €57 million move from Santos during the summer, though he has notched nine assists.
With Messi still sidelined with a hamstring problem, Martino has called on Neymar to step up his strike rate despite his all-round contribution to the side - although he acknowledges the Brazilian is unlikely to match his team-mate's scoring record.
"He should score more goals than he has so far," the Barca boss said.
"We don't analyse any player simply by the goals he scores and lays on - it is a question of all facets of a player's game.
"But at the moment the only question about Neymar is his finishing.
"Neymar is a player who fills all facets of play. He's not a goalscorer with the characteristics of Leo, but he'll give us the same sort of goal return as Pedro, Alexis [Sanchez] and Cesc [Fabregas]."
Barcelona take on Celtic on Tuesday knowing a positive result will see them top the group and Martino has urged his side to fight for the win following a disappointing recent run of results.
"We have to finish first in the group. We must get away from the idea of a comfortable game - every game is uncomfortable, and has consequences," said the Argentine.
"What we need is to be precise, we imagine we'll play a game 30 metres from goal and we'll have to be precise to avoid the counterattacks which Celtic will surely use."
