Star playmaker Benji Marshall says the Dragons are gathering the belief and momentum for a push at the NRL finals.

St George Illawarra are gathering the necessary momentum and belief for an NRL finals push, according to star five-eighth Benji Marshall.

After a mid-season slide following a promising start to the year, the Dragons have won three of their last four matches to move within striking distance of the top eight.

Marshall believes their impressive last-start win over Melbourne has given them the confidence to go on with it.

“I believe we can make the finals and as a team I think we are starting to believe that a bit more every week,” Marshall told AAP on Thursday.

“I think before it we probably didn’t know where we were as a team.

“We knew we had improved a lot, but against a top four professional team, we didn’t know where we stood.

“But to beat them and to beat them the way we did, grinding it out, is probably a reflection of where we could be if we played like that every week.

“We realise we have got the potential to beat good teams we just have to do it every week.

“We need to win six of our last 10 games – something like that – we need to beat the Cowboys this week, then we have the bye and we start again.”

Ahead of the Dragons’ Reg Gasnier tribute match at Kogarah Oval against North Queensland on Saturday, Marshall said he felt he was improving with every game since his round-10 debut for the Red V and was happy to play second fiddle to Gareth Widdop as St George Illawarra’s attacking general.

“I’m enjoying watching Gareth grow because as a leader he wants to to be in control and he wants to get his hands on the ball,” Marshall said.

“He probably didn’t get that at Melbourne, he didn’t get the ball whenever he wanted it.

“It’s good to see him building, he has definitely got a lot more in him, I’m just happy to be a part of it.

“I sort of control the direction of the team and where we are trying to attack on the field and if Gareth wants the ball, he gets it.

“When I played in the past I played that role where I took the ball away from the other halves.

“So I’m just trying, when it is my way to go, to take the ball my way but if Gareth wants the ball I will let him have it.”
