Central Coast Mariners delivered a footballing lesson in racking up a comprehensive victory over a North Queensland Fury team which included Robbie Fowler.

"Our finishing was outstanding. On paper it looks like a very easy win, but I can assure you it was very hard," said Mariners Manager Lawrie McKinna.

"They put us under pressure and hit the woodwork twice. Danny Vukovic showed that he is the best goalkeeper in the league with some of those saves, and we did the job. It's hard to come here, with the travel, the time and the humidity. The boys were running their legs off at the finish.

"It's an achievement to come here and get that many, it's a credit to the team, their finishing, their concentration and their hard work defensively, because they put us under a lot of pressure."

Brilliantly executed goals from Pedj Bojic, Ahmad Elrich and John Hutchinson, as well as a powerful double by in-form striker Nik Mrdja confirmed back-to-back victories for the first time this season.

More significantly, the club enjoyed its most lucrative day at the office in history, scoring five goals in a Hyundai A-League match for the first time ever.

"We've done well against teams at the top of the league but struggled against teams at the bottom. Although there's not much in it we've sometimes taken our foot off the pedal, and it was a big mental focus to get back-to-back," said McKinna.

The win provides a huge confidence boost for United's sister team, who will head back to their Bluetongue Stadium on Friday for the first time since the 3-0 victory over the Gold Coast back in October. Perth Glory will be the visitors.

"Going back to Bluetongue on the back of a great run is great for us. We have played five games (away from home), three wins, Brisbane, Melbourne and Fury, a draw against Adelaide and we got beaten by Newcastle.

"It's a huge achievement for the boys getting that form on the road, but going back-to-back gets that momentum going, it's a huge win for the club," McKinna said.
