Melbourne Victory coach Ange Postecoglu impressed with Daniel Mullen's debut for club The Central Coast Mariners and Melbourne Victory have shared points after a controversial 1-1 draw. Daniel Mullen (L) and Spase Dilevski of the Victory compete for the ball during a Melbourne Victory A-League training session at Gosch's Paddock. Melbourne Victory coach Ange Postecoglou is sick of hearing about Central Coast's transfer woes, saying the Mariners don't have too much to worry about. DANIEL Mullen has been cleared to face Central Coast Mariners on Saturday, in a game that could decide Melbourne Victory's minor premiership fate. Striker Archie Thompson will be given until Friday to prove his fitness but remains in serious doubt. Mullen limped off in the 64th minute but Ange Postecoglou said the jet-lagged defender had just suffered cramp. Perth Glory offered Victory a lifeline by beating the Mariners 2-1 to keep Melbourne within six points of the league leaders. Mariners coach Graham Arnold described it as the worst performance on his watch, a result that keeps the race for direct Asian Champions League entry wide open. "It was probably the worst performance since I've been at the club," Arnold said. We were totally out-enthused and we were second to everything. Scott Galloway's superb performance at left back was one of the highlights for Victory in the 2-1 loss to Western Sydney, as was Mullen's debut alongside captain Adrian Leijer. Postecoglou said Mullen will be fine while Thompson is in doubt for the Mariners. "Tough to say at this stage (with Thompson), we'll assess him as we go along but probably more unlikely than likely," he said. It's his (Mullen's) first game, we're obviously changing the team a fair bit and I think he's the 17th player to debut for us. We've still got six important games to go and to keep him out there any longer then an hour would've been silly of us. I thought he was good while he played and I'm sure he'll be an asset for us.
