Tomorrow is the biggest game of the season for both Central Coast Mariners and Western Sydney Wanderers. To the victor, temporary relief. To the loser, immense pressure...
Central Coast are winless after six games and, despite some narrow losses against highly rated teams, have the worst defence in the league.
But against Western Sydney they garner their best opportunity so far, with the Wanderers reeling off a 4-0 demolition at the hands of Melbourne Victory.
That result, and the Mariners own valiant efforts against reigning premiers Sydney FC, is enough to keep Mulvey looking at the bright side.
"All is not lost," he said. "It's all optimistic, we pushed Perth Glory to the last minute and then we lost at home to Sydney FC, who are among the strongest teams in the league.
"Potential is a big word - we've got to phsyically do it. The biggest part of my job is to make sure we don't lose that belief. We just fell short because of the decisions we make on the field."
The Mariners were without arguably their three biggest players - Kalifa Cisse, Ross McCormack and Tommy Oar - in the 2-1 loss against Sydney FC.
Apart from Cisse, it's doubtful Mulvey will have many options up front against an equally porous defence to his own.
But the 55-year-old isn't making excuses, attempting to remain positive at every opportunity.
"Once we get that one win, we'll shoot up the table,:" he said. "Cisse's back in the squad I'm sure he'll play, McCormack's a lesser chance. Matt Simon will be starting tomorrow.
"Tommy Oar's going to be out for a couple of weeks still, the Wellington game will probably come to early for him.
"There is an upper echelon of the A-League at the moment, but it's a very even league and it comes down to decision making.
"We're learning, but it's a question of how quickly can we learn."
