The Brazil captain struck twice, as did Lionel Messi, in the rout at Estadio Manuel Martínez Valero – the duo now have 19 and 31 goals for the season, respectively.
The result leaves Luis Enrique’s side just a point behind Liga leaders Real Madrid and Neymar is confident they can now push on and put together a serious run of results after bouncing back from defeat to Sociedad with three straight victories, and 13 goals in the process.
"I’m very happy and pleased about everything," said Neymar.
"I’m very happy with the season I’m having. I am always improving. With our attitude, it’s hard to lose.
"Elche started the strongest and they are a good team at home, but eventually we played well and got the win.
"Now we have to keep doing it."
There have been numerous reports of unrest amongst the squad following a patchy start to Luis Enrique's tenure.
Barcelona have scored 18 goals against Elche this season in all competitions, six more than versus any other side, and are now on a run of six consecutive victories in all competitions.
On Wednesday they take a 1-0 lead to Madrid for the second leg of their Copa del Rey showdown with current Spanish champions Atletico.
