Pakistan, after back-to-back defeats to Australia and India, find themselves in danger of being out of the race to the semi-finals. Wahab, however, is confident of his team's revival as they take on South Africa at Lord's on Sunday.
"We have to lift ourselves. We are each other's strength. We are all good friends and know that only 15 of us can lift the team which not even our family members can do. Pakistan plays better under pressure and we will qualify for the finals and semi-finals," he said.
The left-arm pacer believes that lack of wickets with the new ball hasn't helped the team's cause in the previous two games. "As a bowling unit we are trying hard, We are all focused to do well in the South Africa match. You need wickets upfront in England but we were not getting that.
"Our focus is on beating South Africa, and we know we shouldn't get ahead or think about the future. We need to go one by one by what to do everyday. On what we do in the now and not what is happening elsewhere. We shouldn't be thinking about the future," he added.
Wahab, who picked up three wickets against England at Trent Bridge - his team's only win at the World Cup so far, also thinks that 'handling the pressure better' will be the key for both the teams, when they face-off on Sunday.
"Execution of skills is everything," he said. "They have failed in that aspect as well like we did, we had matches we could have won. In this match it depends on who handles pressure better and plays better. They will win."
The 33-year-old who had produced one of the finest spells in World Cup history, when he bowled a series of short-balls at Shane Watson in the quarterfinals of the previous edition, is confident that his team will rise up from their mistakes. "Good teams are those that discuss and talk about their mistakes openly to each other and we've done that. We will make up for our mistakes."
