The A-League leaders trailed early after Oriol Riera's strike but hit back with an Adrian Mierzejewski double and Bobo goal to clinch the win which Arnold said they deserved.

"Fantastic performance. I thought we dominated the whole game," Arnold told Fox Sports.

"We had the majority of the play. The boys did fantastically well to back up after Wednesday night and put in a performance like that."

Arnold was full of praise for Mierzejewski who put in a Man of the Match display.

"Adrian is a player who is all over the field," he said.

"He pops up everywhere. He's hard to contain when he drifts all over the park.

"He's settled in brilliantly well. We work extremely hard on playing with two 10s, two sixes and two nines. our full-backs are very important."

Sydney are next in action away to second-placed Newcastle Jets on Saturday.
