The future of All Blacks coach Ian Foster remains murky after the New Zealand Rugby chief executive gave a bizarre press conference following a famous win at Ellis Park. Mark Robinson refused to guarantee Foster's survival and said he would meet with All Blacks management upon their return to NZ before making a recommendation to the NZR board. It seems almost certain that Foster would have been sacked if the All Blacks had lost in Johannesburg - following three straight previous defeats - but Sunday's fighting 35-23 upset win over the world champion Springboks has significantly muddied the waters.

He called a press conference in the interests of "transparency" but the Q+A session with reporters raised more questions than answers. Crusaders coach Scott Robertson is the popular pick to replace Foster but Joe Schmidt and Warren Gatland are other options if the axe does indeed fall.

"We're proud of them. It was really a critical moment in the development of this team. "We'll be making no further comment until that time which will likely be the middle or later of the week coming up. " Robinson said he had been communicating regularly with Foster. "We believe we know where we stand. We just have to work that through with him," he said. "There's a huge amount of passion and speculation, we appreciate that. . . the appointment of the coach is the board's responsibility. "Management provides insight. We will provide that to them. We're trying our best to keep people informed the best we can. " After initially saying that he had "no idea" whether he would keep his job, Foster told media that he expected to be the All Blacks coach for their next Test against surprise tournament leaders Argentina in Christchurch on August 27. Defending champions NZ are last although all four teams have a one win, one loss record. "He's (Robinson) got a job to do, but I'm about to hop on a plane, go home, and probably mow the lawns around the pool. I'll be giving feedback, no doubt," Foster said. , "My expectation is I'm the All Blacks head coach and I'll be going to Christchurch and assembling a team until I'm told anything different. I certainly feel I've got the support and backing of the All Blacks and I believe I've got the support… "I guess there are processes they want to go through to categorically say that. What I do know is to coach this team you have to have categoric support. " Foster also gave an insight into how the saga had affected him. Before Ellis Park, the three-time world champion All Blacks had slumped to a historic low of fifth in the world rankings. "It has been pretty vicious," Foster said. "There has been a lot of onslaught, particularly from our New Zealand media. "They've got high expectations of us and they've made that loud and clear. "They've clearly come very strong at me as a person. Some of them have even called our selections pop gun which I found quite insulting for players that give everything to play for their nation.
