The South Africans defeated England 2-0. The South Africans are now ranked #1 in International Test cricket. They are looking very fierce. The World Cup will be next on their agenda.
England has been on a downward trajectory for a while. It was shocking to see them lose 3-0 to Pakistan recently. Though, they fought hard to save the recent Test and their ranking, the bowling fire power of the South Africans was too much.
Kallis must be thinking of the World Cup. The ODI version of it.
