South Africa has won two back-to-back Test matches and whitewashed Sri Lanka in the Series. South Africa are in very good form because they won today's match with a huge margin of 100 plus runs against Sri Lanka. Haris Rouf is also in good form but Pakistani selectors dropped Sajid Khan from the test squad. Sajid Khan was the top performer by picking most of the wickets and was the player of the series against England. South African pitches may more favor fast bowling maybe that why Sajid Khan was dropped but i think Sajid Khan was mandatory in the team and more dangerous for South African batsman.

I think if South Africa win this series against Pakistan, then there have enough chances to qualify for the final of the World Test Championship, but if Pakistan wins this series, then South Africa may not qualify for the final. Currently South Africa is in top position on the point table with 63 points, while Australia is in second position just 3 point difference and India in third position on the world test championship point table. South Africa's victory in this series against Pakistan will help to qualify for the final of the World Test Championship.
