Arnold: More to come from rampant Mariners
Daniel McBreen netted a hat-trick and Tomas Rogic claimed a brace in the A-League match at Bluetongue Stadium as the Mariners ran rampant against Sydney, who were without marquee man Alessandro Del Piero through injury.
It was quite a contrast to Central Coast's previous attacking display, when they battled to a 1-0 win over Melbourne Heart last Sunday.
"I felt that performance was coming on Thursday," Arnold said.
"The way they trained Thursday was nearly the best I have seen since I have been at the club and you could see the focus was there.
"It's a new system and still a work in progress. I think that we can better in transition to attack. We worked hard on that this week. The way I tried to build our new system is always about our defensive structure and our defensive structure is always about transition to attack.
"With that system we have got an extra striker and we are trying to take a bit of workload of Tommy (Rogic) to give him more power when we get the ball.
Despite the 'work in progress' remarks, Arnold said he felt his side could has won 10-3.
"It was a really open game," he said.
"I thought we had more chances we could have converted. And they probably had more they could have converted as well."
Discussing the absence of Sydney FC superstar Del Piero, Arnold added: "As I said to boys the whole week, 'I don't care what players Sydney FC have got in their dressing room ... It's about us and what we do.
"We will have a plan if Del Piero plays and if he doesn't that's life and I will always judge us on our performance not what the opposition do."
