With every game a virtual shootout, both the former winners will be eager to make a head start in the tournament which is being held for the last time.
As World Cup champions, India will have more than reputation to defend in the 50-over format contest. They have not played a limited over international outside the sub-continent in the last 15 months but the two big wins in their practice matches against Sri Lanka in Birmingham and Australia in Cardiff will give the Indian team management a fair idea of the conditions to confront.
Although history never counts in international cricket, India have a good record against South Africa in the Champions Trophy. India lead 2-0 in head-to-head having won by 95 runs at Nairobi's Gymkhana ground on October 13, 2000 and by 10 runs at Colombo's Premadasa Stadium on September 25, 2002.
With two out of the four battle-hardened teams qualifying for the semifinals, all matches in group B are expected to be closely-fought affairs.
Except Pakistan, India, South Africa and the West Indies have won the Champions Trophy at least once each and hence more than just pride will be at stake in the last edition of the tournament that began as the Mini World Cup in Dhaka in 1998.
