A sense of belief is starting to build for perennial NRL underachievers Gold Coast following back-to-back wins, according to coach Garth Brennan.

The Titans made it consecutive victories for just the second time this season by ruining Robbie Farah’s return to the Wests Tigers with a 30-18 triumph at a soldout Leichhardt Oval on Sunday.

The two points lifts them equal with Canberra and the Tigers on 14 points on the edge of the top eight with just eight games remaining.

Asked whether he could feel some momentum building in their season, Brennan said: “I’m not sure so much momentum. Probably a bit of belief…believing that they can win and they’re good enough to come up with the right results.”

Brennan, who is in his first season as an NRL coach, insisted his side are also showing genuine signs of improvement after losing seven of nine games before their previous-start win over Canterbury.

They can narrow the gap on eighth-placed rivals Brisbane in next week’s derby.

“I said at the start of the year we’ll be a better team at the back end of the year than we were going to be at the start of the year, and that’s starting to come together,” Brennan said.

“They’re working hard, starting to trust each other, believe in each other and believe in the process that I’ve brought in.”

Brennan got plenty of key contributions against the Tigers, but his Queensland State of Origin pairing of Jarrod Wallace and Jai Arrow were immense with a combined 365 metres.

Wallace’s effort comes after being criticised for his performances in the opening two Origin games.

“I thought Jarrod was strong today. He carried the ball strong, and that’s my game plan for Jarrod. To carry the ball, take the metres and he’s got a pass in him as well,” Brennan said.

“Whether he stuck to the plan that (Maroons coach Kevin Walters) wanted him to do or not, I don’t know. You’d have to ask Kevvie that.

“But the job that Jarrod did for me today was enormous. I’m sure he’ll do the job if given another opportunity.”
