India have become the top Test team in the world in the new ICC rankings thanks to Australia's series whitewash at the hands of Sri Lanka.
Steve Smith's men were thrashed in Colombo on Wednesday to complete a 3-0 series defeat and that result sees India propelled to the top of the Test Championship.
Pakistan move up to second in the rankings, just a point behind India, after fighting back to seal a 2-2 draw against England by winning at The Oval, with Australia now third and England fourth.
However, if India are to retain top spot in the rankings they have to win the fourth Test against West Indies, which begins in Port of Spain on Thursday and batsman Ajinkya Rahane says the team is focused on being the top-ranked Test team in the world.
"Our goal is to play attacking cricket and dominate West Indies here because we have been playing good cricket and it is important to finish well on this tour," he said. "3-0 will be very good and yes, our long-term goal is to be the number one team.
"Right now it is important to stay in the present moment. We want to express ourselves in the middle. That means we want to dominate here again like we did in the three Tests.
"It is important to be in that process regularly and think about achieving the number one ranking as a team."
Pakistan will lead the ICC rankings for the first time if India fail to beat West Indies.
