The deed is done. A Test series has been won. A delighted Virat Kohli will enter the famous Queen’s Park Oval in Trinidad on Thursday, pleased with the fact that his team has wrapped up the series before the final Test.

His team are 2-0 up and have been, by far, the better team. The team’s performance in the third Test, especially, will please the captain to no end – the match seemed to be meandering towards a tame draw with West Indies at 202/3, before Bhuvneshwar Kumar seized the moment from nowhere in a fantastic spell to bundle Jason Holder’s team out for 225 and consign them to another defeat.

After Sri Lanka's whitewash of Australia on Wednesday, India is also the No. 1 Test team in the world. But it is not all over. Before they embark on a long home season, there are still a few threads to untangle for Kohli and his young side.

Retaining the No. 1 rank

For a team that struggled in Tests till very recently, India has completed a remarkable metamorphosis to reach the top of the table in Test cricket.

Now comes the hard part: ensuring that they remain on top. India may be No. 1 right now in Tests, but that could change in a matter of days. If they fail to win the last Test and the series 3-0, Pakistan will displace India from the top.

While that by itself should be motivation enough, Ajinkya Rahane and Ishant Sharma have already previously indicated how much the No. 1 ranking meant to them. After getting to that position after so much hard work, they are not going to let it go very easily, so expect no let-ups from India at Trinidad.

The Rohit Sharma question

Will Virat Kohli continue with Rohit Sharma in the squad? From the vibes he gave after India won the third Test, it seems he will. The Indian captain insisted that Sharma could only be slotted in at the No. 5 position in the batting lineup, and then went on to justify rejigging the batting order to accommodate the Mumbai batsman.

Sharma definitely has his captain’s confidence, but he will be under pressure. Critics have lambasted his inclusion in the squad, especially after he got only nine runs in the first innings. The fact that he got into the squad, in place of the reliable Cheteshwar Pujara, has not gone down well with many. He needs a big score before the action shifts back home.

Ravindra Jadeja, Amit Mishra or both?  

There is also the bowling combination for Kohli to think about. Bhuvneshwar Kumar will be a likely starter in Trinidad after his match-turning spell of 5/33 gave India victory. Kohli had included Jadeja in the team in the third Test in Amit Mishra’s place, possibly to shore up the batting line-up. Jadeja was economical, if not deadly, picking up two wickets in the match, but failed with the bat, scoring only six and 16 respectively.

The pitch at the Queen’s Park Oval is supposed to be spin-friendly, according to the curator. If that proves to be the case, will Kohli bring Mishra back again? Or, it sounds unlikely, but it is something the Indian captain could do – include both Mishra and Jadeja in the squad and sacrifice a pace bowler.

Time for Shikhar Dhawan to step up 

Since his 84 in the first innings of the first Test at Antigua, Shikhar Dhawan’s spell of scores read 27, 1 and 26. Like Rohit Sharma, he is another one of those players whom Kohli backs to the hilt, but the situation has now become more complicated with KL Rahul displacing Murali Vijay as the other opener in the squad. Vijay has been one of India’s best Test batsmen over the last two years and he has good reason to feel hard done by. Dhawan needs a big score to cement his spot in the team, and he needs it fast.
