Sharing the points with the Mariners would normally be regarded as a handy result for the Phoenix but it still left them five points off the play-off pace and with the prospect of needing wins against two of the powerhouses, Melbourne Victory and Brisbane Roar, in their next two games.
Brisbane Roar lead the A-League points table with 30 points, followed by Western Sydney Wanderers 26, Central Coast Mariners 21, Melbourne Victory 20, Perth Glory 19, Newcastle Jets 19, Sydney 19, Adelaide United 17, Wellington Phoenix 14 and Melbourne Heart 5.
Adding spice to Thursday's training at Memorial Park is the fact it will be the last chance for players to impress Merrick before he confirms his starting line-up for the Melbourne Victory match.
Two members of his squad desperate to make a favourable impression will be Carlos Hernandez and Kenny Cunningham, both of whom are wanting to make every post a winner as they seek selection in the Costa Rican World Cup team. It was a powerful left-foot strike from Cunningham that produced Phoenix's only goal against the Mariners.
Other relative newcomers to the Phoenix sure to attract special interest will be a former paramedic from Spain in Albert Riera who has already been labelled as their most influential player and Roiy Krishan, who became the first Fijian to play in the league when he came off the bench in the Mariners game.
