Orlando Pirates confront a Sfaxien side still looking for their first win of this year's group stages after two games. They played to a 1-1 draw against AC Leopards a fortnight ago, adding to a 1-0 defeat to Zamalek.
“It is going to be an open game I feel and I think with the speed we have up front I think we can capitalise on that to use our strength we have," said Erasmus.
"We have been following them. It's going to be a long trip but we are all prepared and we are looking forward going there and collect three points we deserve."
Erasmus, Bucs' top scorer in 2014/15 with 16 goals, believes they have to "want it more" to bag all three points in Tunisia following the home defeat to Zamalek two weeks back.
“We have to do what we normally do and that is putting in the hard work, running the extra mile and wanting it more than our opponents."
