South Africa, England: As South Africa and England clash in the first quarter-final of the International Cup tomorrow, both captains are confident to win the match to play the semi-final.
``We've to win ... we'll win,'' said South African captain Hansie Cronje who is without two regular specialist bowlers in Allan Donald and Shaun Pollock in the side.
After a practice session today, Cronje said despite the absence of some regular players, his squad has the ability to show all-round performance to snatch victory against England.
About his strategy to face the one-day specialist England team, he said it won't be of any special consideration.
``As Dhaka is an unknown venue for us, we'll formulate the strategy after watching Zimbabwe-New Zealand match... seeing how are the pitch, field and environment,'' the South African skipper said.
South Africa had a night practice at the games venue, Bangabandhu National Stadium, on Friday and its captain described the newly-installed floodlight as very good.
Calling the England team a ``balanced'' side, Cronje on Friday had said there is a 50:50 chance for both in the Sunday's first quarter-final.
England's captain Adam Hollioake also echoed his South African counterpart. ``The match has a 50:50 chance. But we're confident to win,'' he said after a practice session today.
The South Africa-England match will begin at 2 p.m. at Bangabandhu National Stadium.
