As we turn for the second half of the A-League season, the contenders are being separated from the pretenders.

1. Central Coast Mariners. They're the A-League's best team and only the lottery of the finals stands between Graham Arnold and a much-coveted (and much-deserved) championship. Their win over the in-form Wanderers was a masterful coaching display.

2. Melbourne Victory. Three wins in their past four matches has the Victory within just three points of the top two. Marcos Flores' scintillating game against Wellington couldn't be more timely. They look unbeatable at home.

3. Western Sydney. Having performed brilliantly in the past month, the loss to Central Coast hasn't taken off too much gloss. The finals are now well in their grasp. Going to New Zealand this week is a test of their mettle.

4. Perth Glory. Annoyed as they'll be at not clinching the result against a desperate Sydney side, Ian Ferguson's side appears to have grown in confidence, registering nine shots on target. A double for Shane Smeltz is a great sign.
