"Look at the volume of cricket that is being play these days, it's absolutely outrageous. We simply know from the South African point of view that we can't afford to play Dale Steyn and Morne Morkel in all three formats of the game. I think we have seen youngsters who are flying through the ranks," Donald said.
"What it does is it fasttracks a lot of good young bowlers or batsmen very quickly into the game. It's just that the skill level doesn't stands still for no one. You need to adapt very quickly. At the moment, we have Chris Morris, who has just come onto the scene. He is doing exceptionally well for Chennai. Before a Test series ends, you start thinking of T20s and ODIs. So, it's tough for a cricketer but at the same time, you need to adapt quickly," he added.
Warriors are currently placed at the bottom of the points table with just two wins from 11 matches they have played so far.
"We know we are under pressure; we need to won all five games. We played some extra-ordinary cricket in the competition but at the same time, our decision-making under pressure hasn't been all that good. It was not up to the mark. We need to show tomorrow what a quality outfit we are," he said.
"We are in a position where we have got five games left in the tournament and we are here to play for pride. We certainly cannot worry about whether we are at home or away. We cannot worry about what records other teams have at home. We got to make significant play tomorrow," he said.
