Interim Perth Glory coach Alistair Edwards says his side can't afford to settle for a draw in Saturday night's A-League clash with Melbourne Victory at AAMI Park.With just two rounds remaining, Perth sit three points adrift of sixth-placed Newcastle and fifth-placed Sydney.The Jets' place in the top six appears the most vulnerable given they have only one match remaining - against runaway leaders Western Sydney.That means a draw against Victory and a win in next week's home clash with Adelaide might just be enough to sneak Glory into the finals.But Edwards, who watched his side sputter to a 2-1 home loss to lowly Wellington on Sunday, is eyeing off nothing less than two wins from two games."Our best form of defence is attack, and we'll be going over there to try to get the three points," Edwards said.Perth's chances against the Victory have been boosted by the upcoming schedule of international matches.Although Glory will be without star striker Shane Smeltz (New Zealand) and defender Michael Thwaite (Australia) this week, Victory will be missing their Socceroos trio of Archie Thompson, Marco Rojas and Mark Milligan.Edwards said defender Steve Pantelidis had recovered from a heel injury and would replace Thwaite, while Travis Dodd is in line to take Smeltz's spot in the starting line-up.Meanwhile, caretaker Phoenix coach Chris Greenacre has had a change of heart, and says he is now contemplating applying for the head role.Greenacre, who took over the reins when Ricki Herbert resigned late last month, initially said he wasn't ready to become a full-time head coach, and would only lead the side until the end of the season.But after experiencing the thrill of Wellington's shock victory over Perth - his second triumph in four games - Greenacre may throw his hat into the ring."This role has given me the idea that a head coach is a way I would like to go," Greenacre said."If it's not now, it's definitely in the future."Before, I was like 'maybe I'm a good No.2, and I can let someone else take the pressure'."But actually the pressure is quite good. It's been enjoyable. It's certainly easier when you have three points in the bag."But if they do bring in a new coach, I'll be right by his side if he wants me there."
