As far as I'm concerned a win is mandatory. We can't lose the first two derbies or we'll never hear the end of it. A draw would be acceptable but it won't feel nearly as satisfying as getting revenge in front of their home crowd
Sure it would be great to win, but I am not looking at it as a must-win derby but rather as a difficult away game against the early leaders of the comp this season who are playing at home. Results often turn on last minute injuries so if we can field a strong squad I will feel confident.
The test of their true form will be when AFC are playing away against Adelaide and Victory. May not matter if they lose away: an average Auckland punter may not care about a loss away that they did not watch. But if AFC keep winning at home in front of their patrons then they will have earned a well deserved boast, and will continue to have good crowds for their home fixtures.
