"I say that with all due respect, we want to make sure he is not afraid of all those sort of things. When you see him on the ball in that front third of the pitch, I think he'll be a handful for anybody in this league."
Totori is a known commodity to football fans in New Zealand through his exploits in the national league, but it was his efforts at the recent Oceania Nations Cup in the Solomon Islands which appear to have convinced Herbert he can hack the pace of the A-League.
As New Zealand's campaign went from bad to worse, Totori couldn't stop scoring goals and he netted three times in two outings against the All Whites.
"I think there's an X-factor to him and I think it's pretty hard to gauge three or four years ago when he was here," Herbert said.
"He was the leading goal-scorer in a relatively comfortable position, but we had a good long chat post the Solomons tournament and he's a lovely kid who's very balanced and he appears to me now that he'll be a lot more settled and do well.
"I think he'll be a real handful in the league and we'll take our time with him. They'll all have their ups and downs and I think he's one of the better signings we've made."
Totori said he always wanted to force his way on to a professional roster and believed he could cope with the physical nature of the A-League.
"I think my strength is just speed and I just have to play the ball early, as soon as possible before the tackles come in," he said.
"I've got a game that I'm confident can beat the physical nature of the other teams but for me, I'll be ready. I'll be ready physically as well, so hopefully I can improve by training with the Phoenix. It's a different level and different training from back home and the [ASB Premiership]. We train every day here and it's more professional."
Totori said he was inspired to perform at the Nations Cup knowing there would be plenty of interest from professional sides and he was delighted to land a deal with the Phoenix.
"I'm very excited to be here. The players are good, they're very friendly and I'm very happy."
Totori could form a dangerous partnership with Phoenix forward Paul Ifill this season, although Herbert has indicated he wants to add another striker to his roster before the campaign gets underway proper.
