There are more tricks up James Roberts’ sleeve according to Titans coach Neil Henry.

Titans' magic man a work in progress

His teammates see him as the type of player capable of producing a rugby league magic trick from out of nowhere, but Titans coach Neil Henry insists there is still much for electrifying centre James Roberts to work on.

Henry has been forced into making just the one change to the team that defeated Cronulla 24-22 last week with a two-week suspension to hooker Beau Falloon opening the door for Kierran Moseley to return from a knee injury in the No.9 jersey.

With two tries and a one-on-one strip that directly led to a third, Roberts was the difference between the Titans and the Sharks last Saturday night in Sydney and shapes as a key figure against the Broncos at Cbus Super Stadium on Friday night.

A match-up opposite Jack Reed offers the 22-year-old another opportunity to showcase the blistering speed that has already brought him four tries in the opening month of the season, equal second in the NRL behind the Bulldogs' Curtis Rona who has five.

And while thankful to have such a talent at his disposal, Henry warned that there are other areas of his game that Roberts needs to continue to improve.

"He's got elements of his game that he still needs to work on," Henry said. "It's about being able to produce those repeat efforts. Defensively he's learning all the time but there's no doubt he's got great speed and he can get to a ball.

"It was pretty fortuitous that [the match-winning intercept] went into his hands and there are not many people that are going to peg him back from there.

"He showed real good skill to get onto that grubber kick and force it in the in-goal and he's a special player but he still acknowledges that he's still got to work on his game."

Titans winger Anthony Don spoke of the relief in the dressing sheds following their win over the Sharks and acknowledged the critical role Roberts played in securing their first win of the year.

"It's the type of players you need in those close situations," Don said. "Jimmy scored two tries and he one-on-one raked for the other try so he was involved in three of our tries and if Jimmy wasn't there doing those plays we might not have won.

"It could have been a loss but we were lucky to escape with Jimmy Roberts' intercept.

"It's awesome having him in our team and someone you can throw the ball to and hopefully come up with a magic play.

"There was a lot of relief after the game. We were just stoked that we got the win and everyone was pretty jubilant about the victory."

The Titans conjured another dramatic escape act when the Broncos last visited Cbus Super Stadium in Round 6 last season and Henry said any continued disregard for possession will be punished by the Broncos.

"There's no doubt we need to be a fair bit better than we were last week," said Henry.

"Our completion rate is still not good enough, it was down in that low 70s and the Broncos I think were at 88 per cent and only made five errors against the Warriors.

"On the back of three wins on the trot they've got a bit of momentum as well."
