Mahendra Singh Dhoni's side currently sits in second place on 118 ratings points, seven ratings points behind Andrew Strauss' side, while Michael Clarke's men are in fourth position on 103 ratings points. Third-ranked South Africa, which leads sixth-ranked Sri Lanka 1-0 in a three-Test series, is on 116 ratings points.
As such, shuffling of the pack in the middle of the Championship table could be on the cards, depending on how the series Down Under (which finishes on 28 January) and in South Africa (which finishes on 7 January) pans out.
If Australia wins all the four Tests, it will jump to 111 ratings points and India will drop to 111 ratings but will still be ranked above Australia by a fraction of a point. In case of a 3-1 win for Australia, the home side will rise to 108 ratings points and India will drop to 113 ratings points whereas a 2-2 draw will mean Australia will gain two ratings points and India will drop two ratings points.
In a sharp contrast, if India makes a sweep of the four-Test series, it will move to 122 ratings points and will narrow the gap with England to just three points. A 3-1 victory for India will put it on 120 ratings points dropping Australia to 101 ratings points, whereas a 2-1 series win will earn Dhoni's side one ratings points.
