The Spain star says his side will do their utmost to help the Brazilian add to his recent goal glut and is determined to see out 2013 with wins in their remaining two gamesAndres Iniesta says it is up to the rest of the Barcelona side to keep Neymar scoring goals following the Brazilian's double in the 2-1 win over Villarreal.
Neymar added to his midweek hat-trick against Celtic with a penalty and a well-taken finish to move the Blaugrana three points clear of Atletico Madrid at the top of La Liga prior to the Rojiblancos' meeting with Valencia on Sunday.
Neymar's booking on Saturday - his fifth of the season - means he will now be forced to serve a one-match ban, but Iniesta feels it is vital his side do their best to keep the former Santos man among the goals this season as Lionel Messi remains sidelined with injury.
"He can decide matches," Iniesta said of Neymar to the club's official website. "We'll try to make sure that the player's goalscoring streak continues as long as possible."
Barca were forced to work for the points on Saturday after Mateo Musacchio's goal had threatened to snatch a draw for the visitors, and Iniesta has urged his side to pick up wins from their remaining matches in 2013 as they look to hit top form under Gerardo Martino.
"It was very difficult but we did a lot to secure the result," said the Spain international, who returned to the starting line-up on Saturday. "We're improving, and we'll continue to improve.
"The main thing is to close out the Copa del Rey tie [against Cartagena] and try to win the three points at Getafe."
