India are favourites to carry on where they left off in Australia and spoil England captain Joe Root's 100th Test in Chennai.

Depleted India defied the odds to come from behind and secure a 2-1 series win in Australia despite being without a host of key players, including captain Virat Kohli.

Kohli returns from paternity leave to lead the side after Ajinkya Rahane filled in superbly in his absence, while Jasprit Bumrah, Ishant Sharma and Ravichandran Ashwin have recovered from injuries but Ravindra Jadeja (broken thumb) misses out.

India are in pole position to seal their place in the inaugural ICC World Test Championship final against New Zealand, but England and Australia can also qualify.

In-form skipper Root will become the 15th England player to win a century of Test caps when the four-match series starts at the M. A. Chidambaram Stadium on Friday.

Ben Stokes, Jofra Archer and Rory Burns return, while Jonny Bairstow, Mark Wood and Sam Curran have been given a rest following the recent 2-0 whitewash of Sri Lanka.

The tourists could be without Zak Crawley after the batsman injured his right wrist when slipping outside the changing room, but Ollie Pope is poised to make his comeback from a shoulder injury.

England have won just one Test series in India since 1984-85, losing four and drawing one since then other than a triumph in 2012.

What are the Test Championship permutations?

The postponement of the series between South Africa and Australia ensured the Black Caps will play in the first Test Championship final.

Kane Williamson's side will face India at Lord's if they beat England 2-0, 2-1, 3-0, 3-1 or 4-0.

England must win at least three matches in India to set up another final against New Zealand, so Root's men are very much outsiders. 

Australia will qualify if England win the series without winning three matches, while they will also take on their trans-Tasman rivals if the series is drawn or India come out on top 1-0.

Centurion Root leading by example 

Root failed to make a hundred for England last year, but the prolific captain showed class is permanent in Sri Lanka.

The 30-year-old made a magnificent 228 in his first innings of the series and struck a brilliant 186 in the second Test, making a strong statement at the start of a hectic year for England.

Root averaged 106.50 as he delivered a masterclass of how to bat against spin and will be relishing the battle with the India attack.

He is just one win away from matching Michael Vaughan's record of 26 Test wins as England skipper and achieving that feat in the Yorkshireman's 100th match would be extra special.

KEY MATCH FACTS

- Four of the last five Test series between the two sides have been won by England, who eased to a 4-1 victory when they last did battle in 2018.

- India have won their last 10 multi-game bilateral Test series on home soil, that run beginning after they suffered a 2-1 defeat at the hands of England in 2012.

- India have recorded five wins to England's three when facing off against each other at M.A. Chidambaram Stadium. India have won three in a row at the Chennai venue.

- No touring side has won at M.A. Chidambaram Stadium during the 21st century (D3 L5) – Pakistan being the last team to do so in the format (1999).

- England are on a run five away Test wins in succession – their longest such run since 1914 (seven in a row between 1911 and 1914).

In-form West Indies middle-order batsman, Jermaine Blackwood, has credited brief advice received from top-class India batsman Virat Kohli as helpful in changing his mindset towards scoring runs.

The 29-year-old scored his first century against England in 2015, a plucky 112 unbeaten in a draw in Antigua.  Following that impressive achievement, however, Blackwood seemed unable to cross the double-digit threshold.  In fact, before finally breaking the streak with 104 against New Zealand, in December, Blackwood had managed to score 10 half-centuries in-between but always fell short of a triple-digit score.

Included in that number were some figures frustratingly well clear of the 50 mark, but falling just short of the 100 mark, when for all intents and purposed the batsman seemed well set to do so.  The tally includes three scores in the 90s.  He scored 92 against Sri Lanka, in Galle, in 2015; 95 against Pakistan, in Abu Dhabi, in 2016, and 95 against England, in Southampton, in July of last year.  Prior to that, Blackwood also registered 85 against England, in Bridgetown, in May 2015.  During India’s tour of the West Indies, Blackwood took the opportunity to seek the advice of run-machine Kohli when the two briefly interacted off the pitch.

“I just asked him how come all the time I score so many half-centuries and just one century, and he just replied, ‘What did you do when you scored the century? How many deliveries did you face?’ I said I faced 212, and he said that’s it, once you can bat some balls you will score runs,” Blackwood recalled.

“I took a lot from that and I’ve always told myself, after that conversation, once I can bat over 200 balls or 300, I’m going to score runs.  Once I’m there, the way I bat, I’m going to score runs regardless of who I’m playing against or where I’m playing.”

Virat Kohli called for "strict action" to be taken after India players claimed they were subjected to racial abuse by spectators during the third Test against Australia at the SCG.

Six people were ejected from the iconic Sydney venue on day four after India paceman Mohammed Siraj reported he was the target of abuse while he was fielding on the boundary.

The India team staff also reported alleged racial abuse of Jasprit Bumrah and Siraj on Saturday.

Play was halted for around 10 minutes on Sunday, with umpires and security guards holding discussions before the spectators were removed by New South Wales Police.

The International Cricket Council (ICC) strongly condemned the reported incidents and offered Cricket Australia (CA) all necessary support with an investigation.

India captain Kohli, who is back in his homeland as his wife is expecting a baby, said action must be taken as soon as possible.

He tweeted: "Racial abuse is absolutely unacceptable. Having gone through many incidents of really pathetic things said on the boundary Iines, this is the absolute peak of rowdy behaviour. It's sad to see this happen on the field.

"The incident needs to be looked at with absolute urgency and seriousness and strict action against the offenders should set things straight for once."

CA head of integrity and security Sean Carroll earlier said in a statement: "Cricket Australia condemns in the strongest terms possible all discriminatory behaviour.

"If you engage in racist abuse, you are not welcome in Australian cricket. CA is awaiting the outcome of the International Cricket Council's investigation into the matter reported at the SCG on Saturday.

"Once those responsible are identified, CA will take the strongest measures possible under our anti-harassment code, including lengthy bans, further sanctions and referral to NSW Police.

"As series hosts, we unreservedly apologise to our friends in the Indian cricket team and assure them we will prosecute the matter to its fullest extent."

India spinner Ravichandran Ashwin claimed India have experienced abuse on previous tours of Australia.

"This is my fourth tour to Australia and in Sydney, especially, we have had a few experiences even in the past," he said.

"I think one or two times even the players have reacted and got into trouble in the past, and that's not because of the player, it is actually because of the way the crowd has been speaking, especially the people close to the boundary edge.

"They have been quite nasty, they have been hurling abuse as well, but this is the time they have gone one step ahead and used racial abuse.

"There was an official complaint lodged yesterday, and the umpires also mentioned it to us that we must bring it to their notice as soon as it happens, on the field, and then they will be able to take action.

"It is definitely not acceptable in this day and age. We have seen a lot, right? We have evolved as a society. This must be definitely dealt with an iron fist. And we must make sure that it doesn't happen again."

Australia are strong favourites to take a 2-1 series lead, as India were 98-2 at stumps on the penultimate day after being set 407 to win.
