In the battle of the beaches United will look to forge further ahead of the pack, while a win for the Mariners could see them land in second place on the Hyundai A-League ladder.

Thwaite, who has played almost everywhere but striker and keeper,  believes United has enough tricks to further apply its dominance.

"Of course the Mariners will want to come after us, but I think we can take advantage of them even at their home ground," Thwaite said. "Amongst the playing group we believe there is at least 30 percent more improvement in us.

"Against the Mariners we will be looking for nothing but the three points."

In all their confidence and brilliance, United have struggled to find consistency as a unit over the first six weeks with niggling injuries and representative duties a continual disruption.

Thwaite, defensive Dutchman Bas Van Den Brink and striker Shane Smeltz are the only players to have started every match for the new club.

As the revolving door continues to spin, Robson and Daniel Piorkowski are out injured, while Tahj Minniecon is on tour with the Young Socceroos, Thwaite only sees opportunities.

"Whoever gets a chance will do the job, we don't even think twice about it because we know that whoever gets a run will get the job done," he said.

With United struggling against Glory it was Anderson who was thrust into the match and quickly began pulling the strings that led a two-goal comeback.

"Anderson has composure that this league hasn't seen yet," Thwaite said. "He came on in the second half against Perth and changed the game.

"He always wants the ball at his feet and like Jason (Culina) he dictates the play."

It remains unseen how Miron Bleiberg will utilise his glut of talent against the Mariners but United will need to be at their attacking best to take the points from a team which has conceded just one goal on its home-turf so far.

Meanwhile, Daniel Piorkowski has suffered a cruel injury blow ahead of this weekend's trip to Gosford with the Gold Coast United defender diagnosed with a fractured left fibula following a training accident on Thursday.

An innocuous tackle and awkward fall left the 25-year-old in obvious pain and an ambulance was summoned immediately to transport the unlucky Piorkowski to hospital for x-rays.

Further tests will be conducted today to assess if there is any further damage before a recovery timeframe can be accurately established.

However, a lengthy lay-off is expected for the former Melbourne Victory man and United Head Coach Miron Bleiberg is left with no option but to begin his search for a temporary replacement player to cover for the central defender's absence.

"It was typical of Daniel to show full commitment in a training session and that's what he did. Sadly on this occasion he has landed awkwardly after a tackle and on first viewing it didn't look good," said Bleiberg.

"Daniel is a lovely guy and a very good player and we are all sad for him. He will be back in time of course, but in the meantime we will need to look for a replacement player to give us cover in the central defensive position."
