I would like to add to my previous post and just say that - at present - Ricki appears to be the most experienced in terms of football (apart from playing on the field), therefore getting rid of him completely would not be conducive to The 'Nix recovery if only one new person (a replacement coach) is employed. Additional, experienced support staff is important. We seem to be doing worse with no Luca Triani but with Greenie instead, which is the main difference in the coaching backroom this season. A good head coach is of course crucial.
Consider the Western Sydney Wanderers who have a newbie coach (Tony Popovic) and are successful on the park. Tony spent many years playing football in Australia (Sydney United in the nineties, and then only with Sydney FC in the 2007-8 season), but crucially played also for many years in Japan (Sanfrecce), England (Crystal Palace) and finally in the Middle East. That means a well-rounded football experience. As the style of football in HAL changes to a more skill-based one, Popovic seems to have arrived as a "young" (he's 40) coach at the right time.
Now contrast that with Ricki Herbert, who simply did not have the opportunities to play abroad that the younger players now have. He may be a good coach in many ways, but had no real exposure to continental European football which coaching in HAL increasingly requires, with decreasing percentage of hoofball and higher percentage of ground passing. If there was additional experienced coaching personnel that Ricki would rely on or listen to, it may have worked; but it is just too early for Greenacre to be that kind of a person, despite his other good qualities (importance high workrate, etc).
He may be expensive, but the Australian professional coach of Argentine origin, Raul Blanco, could be a man to consider as an additional coaching staff member (he was already involved with the All Whites earlier). Instead of sacking Ricki, giving him a support staff may be an answer.
Actually, getting outplayed quite a bit these days
