Walmsley laments Mariners’ defensive lapses

Central Coast Mariners coach Tony Walmsley insists his side must clean up the preventable errors which proved costly in a 4-1 defeat to Melbourne City on Sunday.

The competition’s bottom-placed side enjoyed a shock 1-0 lead at the break but shipped three goals quickly after the restart as hopes of a rare victory faded.

Two free-kicks, a penalty and Harry Ascroft’s indecision in letting a ball bounce all contributed to the turnaround, which Walmsley says will be unacceptable in next week’s F3 Derby against Newcastle Jets.

“That’s not good enough, we need to polish up on those,” the Mariners boss said.

“Two set pieces cost us against Adelaide last week. They’re little mistakes that have a big impact on the result.

“There’s a lot of positivity about where we’re heading. About where we are? It’s really painful.”

While next week’s hosting of rivals Newcastle should see the return of Luis Garcia from bone bruising, the immediate future of fullback Storm Roux is less clear.

Mariners defender Storm Roux is stretchered off AAMI Park on Sunday.

The New Zealand international was taken to hospital after his right leg stuck in the turf when lunging to block a shot in the second-half.

“We don’t really know how he is yet. He’s not in a good way,” Walmsley said.

“It doesn’t look good and it obviously had an impact on some of our guys after the stoppage in play. It’s lower leg and possibly shoulder as well is all I’ve heard.

“I don’t want to speculate too much but (he’s) not in a good way and obviously all our thoughts are with him at the moment.”
