Ricki Herbert believes he's still the right man to lead the Wellington Phoenix despite the struggling A-League club slumping to a new low.The Phoenix were blown away on Saturday night, suffering their biggest ever defeat in a 7-1 loss to an Alessandro Del Piero-inspired Sydney FC.Wellington's previous biggest loss was a 6-1 defeat to Adelaide in December, 2008.They sit last on the A-League ladder after four straight losses, equalling their worst losing streak from October 2007.While Herbert had received wide praise for his job at the helm of the Phoenix and the New Zealand national team, recent results have put his position under pressure.However he's hoping the club will stick by him."I'm as hungry as ever," Herbert said after the loss."There's a lot to build about this club and yeah, it's tough at the moment, very, very tough but I'm just as keen to get us out of this."Herbert branded Saturday's performance "totally unacceptable at both ends of the pitch" as his side copped four goals from Del Piero and wasted a handful of good chances at the other end."That's the most disappointing performance by a team that I've had at the football club," Herbert said."It's not like we didn't have goal scoring opportunities, we just weren't good enough to take them and at the back we were just exposed by better players."Herbert acknowledged he did not have an "x-factor side" but said several players were not delivering 100 per cent."The league's growing and you've kind of got to grow with it," he said.
