Preview: Central Coast Mariners v Adelaide United

The importance of this match will be very much determined by what happens earlier in the weekend. Central Coast could be well and truly safe inside the top four if Wellington lose and would have nothing to gain from this match given they would finish fourth regardless.

Analysis The importance of this match will be very much determined by what happens earlier in the weekend. Central Coast could be well and truly safe inside the top four if Wellington lose and would have nothing to gain from this match given they would finish fourth regardless.

It's a different story for Adelaide, which will most likely need to win this match to keep its hopes of winning the Premier's Plate alive. The Reds lead Melbourne on goal difference, but should the Victory secure a hefty win over Wellington, then Adelaide will need to at least match that result to ensure it stays top. The other concern is Queensland, which could put considerable pressure on Adelaide with a win over Sydney on Saturday night.

In that situation, a loss or draw could see the Reds miss the double chance and then play the Mariners the following week in a sudden-death two-legged tie.

So there is a lot for Aurelio Vidmar's men, who have won just one of their past four, to lose this week. But at least they will know exactly what they will have to do.

Cassio returns in a timely boost, while Lucas Pantelis and Robert Younis are also back in with Sasa Ognenovski suspended and Matthew Mullen left out.

Ognenovski's absence is a big one for Adelaide, which has conceded six goals in two games against Central Coast this year. In the first game, they drew 3-3, while the Mariners pounded the Reds 3-0 the last time they met.

Suspensions have hit Central Coast hard in this match with Dean Heffernan serving the first of a two match ban and Andrew Clark picking up a fifth yellow card in the heavy defeat against Melbourne. Nigel Boogaard comes in, along with Greg Owens, while two youth league players, Brady Smith and Matthew Lewis will be blooded if needed,

Lawrie McKinna has a few defensive worries of his own with his side having conceded seven goals in its past two matches against Melbourne and Queensland. The momentum has quickly slipped away from the Mariners and while they will most likely make the finals, McKinna needs a good result here to have his side headed in the right direction for February.
