Cape Town City snapped up the highly-rated hitman after he was let go by his Portuguese club Vitoria Setubal at the end of 2018.
And the former Orlando Pirates and Feyenoord striker is set to make his City debut at another ex-club, SuperSport United, tomorrow (8.15pm).
Asked what Erasmus will add to the club and team as City look to climb up from ninth place in the PSL, Benni says: “He brings the European element for me.
“As much as he is a South African talent, he’s been there and he knows the work that goes into the tactics, he knows the training intensity.
“So a lot of the younger players that we have, they can learn a lot from him."
Benni experimented with a striker-less formation towards the end of last year.
But the boss says that while the 28-year-old marksman from Die Baai has the skills to play in the “false No.9” position, he will not use the ace as an out-and-out striker.
Bafana Bafana's leading goalscorer says: “Going forward, when it comes to the team, I see him as a No 9, an out-and-out striker. Or a No 10 because he has the intelligence.
“So that’s how I’m going to use him.
“I don’t want him to drop into midfield too often because we have players for those positions.”
“Listen, he has the mobility, the speed and the brains to play as a false nine.
"But the reason that we won’t be a false nine is that he is an out-and-out striker. He is a goalscorer.”
Kermit, though, says that he hasn’t given himself a target for the number of goals he wants to score this term.
He says: “I’m not the type to set those targets. For me it’s about enjoying the game and helping the team win. It doesn’t matter who scores the goals, as long as we win. The goals will come, I believe that and that’s why the coach brought me here.”
Meanwhile, City has sent midfield anchorman Mpho Matsi out on loan to Maritzburg United until the end of the season and the club is expected to do some transfer business in the current window.
