I think Quinton de Kock could be persuaded to come back for the next World Cup in 2027, which is co-hosted in South Africa.

I think the South African selection policy is also becoming more flexible, allowing for players to play in leagues around the world.

So there is plenty for him to think about.

South Africa get off the mark as Bumrah sends down an off side wide.

De Kock edges a single to deep third to retain the strike.

South Africa tend to start slowly and use the powerplay to set the foundation. I'm not sure if that will work this time around.

Jasprit Bumrah hustles in for the opening delivery of the innings. In on the pads, De Kock fends the ball away.

Timothy Abraham, a gentleman.

Right then. The South African openers are out in the middle - Quinton de Kock has four centuries at this tournament, can he rack up a fifth?

Virat Kohli is among the India players currently in a group hug on the edge of the outfield the field at Eden Gardens.

That's my signal to grab some luncheon. Mike Peter is here to talk you through the start of South Africa's chase.

My colleague Stephan Shemilt has just pointed out that Virat Kohli follows 61 people on X, formerly Twitter.

One of them is former Great Britain sprinter Linford Christie.

Answers on a postcard...

Sachin Tendulkar on X: Well played Virat. It took me 365 days to go from 49 to 50 earlier this year. I hope you go from 49 to 50 and break my record in the next few days. Congratulations!

The Little Master as humble and self effacing as always...

India batter Virat Kohli: "It was a wicket that was a bit tricky to bat on. So we got a great start and when I got in my job was to keep the momentum. After the powerplay the pitch slowed down and the ball started gripping so my role was different. We want to string together a big partnership and bat to the end.

"We were not thinking we would get to 326 but that's what happens when you dig deep and take the game to the final few overs.

"Me and Shreyas had a lot of practice sessions before the Asia Cup. We said that this was the partnership to take centre stage though the middle overs. We are comfortable rotating the strike against the spinners and putting the loose balls away so credit to him."

On equalling Sachin Tendulkar's ODI century record: "Every opportunity to play for India is a big one and to do this on my birthday in front of a huge crowd is the stuff of dreams. It is something you dream about as a child.

"I am just happy to help the team as much as possible."

On India reaching 326-5: "It is well above par because it was not easy to get hold of in the middle overs. We have to work hard but get a few breakthroughs and the pressure starts to mount. We need to start well with the new ball."

Here's the best bits of Virat Kohli's 49th ODI century, on his 35th birthday.

Has someone at the BCCI prepped a cake?

Hari Ramanathan: To paraphrase Einstein: generations to come, it may well be, will scarce believe that such a man as this one in flesh and blood went more than 1,000 days without scoring an international century.

This match is living up to its billing so far. Now we want to see if South Africa can overcome the demons of batting second.

Pakistan legend Shahid Afridi on X: This is the best birthday gift from Virat Kohli to the fans of team India & entire cricket fraternity.

Virat Kohli is just doing a flash interview so we'll have his words shortly.

Here's the moment when Kohli equalled Sachin Tendulkar's record of 49 ODI centuries.

Virat Kohli cannot quite get under Marco Jansen's final ball and has to settle with a single to finish.

He walks off 101 not out.

Oh, and South Africa need 327 to win this.

You want Kohli to get the record in the semi-finals or final. It wouldn't be romantic to do it against the Netherlands.

A single for Ravindra Jadeja brings Virat Kohli on strike for the last ball. Can he finish with a flourish?

Another big swing of the bat from Ravindra Jadeja to Marco Jansen gives him back-to-back boundaries. That went flying down the ground and beats the dive of David Miller on the boundary.

You wouldn't class Jadeja as a touch player, as a power player. He's just someone who gets the job done. Against pace, against spin.
