Shell-shocked by Gayle's record 47-ball century, England are required to win against the Proteas, to whom they lost 0-2 in the tune-up to the tournament, if they are to progress to the semi finals from Group 1.
The 2010 champions' under-fire bowlers and fielders will be up against a strong rival batting line-up comprising the innovative A B de Villiers - holder of the world's fastest 50, 100 and 150 in ODIs, big-hitting David Miller and the solidity of captain Faf du Plessis, Hashim Amla, Quinton de Kock and J P Duminy.
They were tilted over for 171 as recently as February 21 at the Wanderers Stadium in Johannesburg by the Dale Steyn-less Proteas' bowling attack comprising young tearaway Kagiso Rabada, Kyle Abbott, Chris Morris and Imran Tahir.
South Africa chased the target for the loss of just one wicket with openers de Villiers and Hashim Amla smashing half centuries to help the side complete a 2-0 win.
With Steyn back into the squad after his injury woes, South Africa's bowling attack looks truly formidable, though the track at the Wankhede is a bit different from those back home.
England, for their part, could re-jig their bowling attack a bit and rework on their strategies to stop the South Africans who have, in the past, been saddled with the tag of chokers hung around their neck in ICC events.
