Melbourne Heart coach John Van ‘t Schip wants striker David Williams to deliver on a consistent basis after his three goals help sink Wellington Phoenix.

Melbourne Heart coach John Van ‘t Schip said a few weeks ago that he felt striker David Williams could bring more to the team.

The 25-year-old Australian certainly delivered in Wellington on Sunday.

Williams scored the club’s first ever hat-trick in the 5-0 drubbing of Wellington Phoenix and in the process became Heart’s all-time top scorer with 15 goals.

His three goals at Westpac Stadium gave him a tally of five goals in three matches after he came off the bench to deliver match-winners against Perth Glory and Sydney FC.

There has never been any doubt about Williams’ talent and all three goals against the Phoenix were classy, from his lob over an out-of-position Glen Moss, to his deft strike for his second and finally his curling shot in off the post in the 63rd minute.

But many, including Van ‘t Schip, believe Williams has still to reach his full potential.

“He has to be more consistent. With his experience that he now has in the A-League he has to be important every game for the team,” said the Heart coach.

“Today he showed (the level) he actually can play and how important he can be for the team.

“I’m not expecting him to score three goals every game, but to work hard and to show his talent because he has a lot of talent.”

Dutch midfielder Orlando Engelaar, who returned to the starting line-up after suspension, was another standout for the Heart in their emphatic win – their first on New Zealand soil.

His thunderbolt strike opened the scoring in just the ninth minute and it was his quickly taken free-kick that set up Williams’ first goal 10 minutes later.

“He’s important (to the side),” said Van ‘t Schip. “You can see he’s got a good touch. He’s calm. He’s not at his physical best still… (so) it was important today that we could keep him on the pitch.”

The win in Wellington ended a winless away streak of 22 games but Van ‘t Schip wasn’t getting too carried away given his side remains bottom of the ladder.

“We have to be humble and be prepared for our next game,” he said. “It went all our way this game. Next week we have a very tough game against Brisbane at home.”

Phoenix coach Ernie Merrick said it was vital his side moved on quickly from the disappointing performance ahead of the trip to Central Coast Mariners.

“It’s important that they show resilience to bounce back from that. It’s an important measure of their character.”
