Recovering from a long-term hamstring injury Brosque has not started for the sky blues in the first three games of the A-League season.

Despite only making substitute appearances Brosque has still made a massive impact from the bench, scoring against both the Wanderers and Mariners.

“At the moment I’ve got plenty of choices to make,” Arnold told the Hyundai A-League Official Website.

“What I’m seeing though is after 60 minutes when I bring Alex on or Matty Simon as well, the opposition struggle to contain them.

“Of the nine goals we’ve scored so far in the league, five have come in the last 20 minutes of the game when our fitness kicks in and we bring on Alex Brosque and Matty Simon.

‘It’s about having a strong squad and using all the players and so far it’s working well.”

Alex Brosque has made over 150 appearances for the club and Arnold believes the Sydney skipper can still continue to be vital for the club.

“At the moment we’re building his fitness and making sure there's no slip-ups with what happened to his hamstring,’ the Sydney coach said.

“Alex is in a good head space. He wanted to continue this year because of what happened with his hamstring last year, he didn’t want to finish that way.

“I still think he has another two or three years left in him.”

The Sky Blues come up against fellow unbeaten team Newcastle Jets this Saturday and Arnold has been impressed by Mark Jones’ start with the Jets.

“Mark has been clever by taking over late from Scott Miller, he left the system the same, personnel the same,” Arnold said.

“It will take him time to get his stamp on what he wants.

“At the moment they are undefeated, doing well defensively in the system they are playing and showed great character last weekend against the Wanderers.

“They are dangerous at home so we have to make sure we go there with the right attitude and try and win the game.”
