England go into the match with a 1-0 advantage but Strauss yesterday cautioned against trying to protect that lead.
“We’ll be going in trying to win, it’s as simple as that, we’ll be using the same style that was successful before,” Strauss told a news conference.
“If you go into a test thinking you only need a draw that can be very dangerous because then your mindset can be negative and hesitant and you end up handing the momentum to the opposition.
“In all likelihood, this test is not going to be a draw, so we need to make sure we get ahead and put South Africa under pressure.”
England are likely to field the same team that salvaged a last-ditch draw in the third test in Cape Town last week, but Strauss said he was looking for a performance closer to that of Durban where England won by an innings.
“You’d have to go quite a long way to improve on the performance in Durban but we had our opportunities in Cape Town, we just didn’t take them,” said Strauss.
I’m confident we can take 20 wickets, we showed that in Durban, and the pitch will offer more for the bowlers here.
“But that means there will be more pressure for our batsmen to fight hard.
I felt we didn’t do ourselves justice with the bat in the first innings in Cape Town, but showed a lot of fight and hunger in the second innings,” Strauss said.
South Africa have to win the test to level the series and retain the Basil D’Oliveira Trophy and left-arm fast bowler Wayne Parnell is likely to get the call for his test debut.
“Wayne has a very good chance of playing, he adds a touch of variety being left-arm and he has pace,” said South Africa captain Graeme Smith.
