From my chats with others in the press box we reckon there at least two Pakistan fans here. That would leave 133,998 supporting India.

They reckon this could be the largest crowd ever at a cricket match.

This ground is a sea of Indian blue. Nobody everybody is in the ground yet because of how long it takes to get in. A fair number are still queuing to get in through the bag searches and security checks.

The umpires head out onto the pitch and collect the ball from the mini truck that we have got so used to seeing ahead of every game now.

Sachin Tendulkar then wanders out and, unsurprisingly, gets a huge ovation from the crowd, slightly stealing the thunder of the current players...

Actually no, here come the players and the decibel level increases yet again. Time for the anthems...

Pakistan's record against India drives their fans crazy. It's not a fair reflection of the rivalry either, but it's one of those patterns you get in tournaments. If you look at the overall records, Pakistan still hold the edge with winning percentage but in World Cups India have had long lasting dominance.

India: Rohit Sharma (c), Shubman Gill, Virat Kohli, Shreyas Iyer, KL Rahul (wk), Hardik Pandya, Ravindra Jadeja, Shardul Thakur, Kuldeep Yadav, Jasprit Bumrah, Mohammed Siraj.

Pakistan: Abdullah Shafique, Imam-ul-Haq, Babar Azam (c), Mohammad Rizwan (wk), Saud Shakeel, Iftikhar Ahmed, Shadab Khan, Mohammad Nawaz, Hassan Ali, Shaheen Afridi, Haris Rauf.

This game sees India face Pakistan on home soil for the first time in 12 years.

In 2011, when the tournament was last held in India, these two sides faced each other in the semi-finals. A 29-run win for India in Mohali saw them reach the final, where they beat Sri Lanka.

But how much do you remember of that 2011 semi-final?

To test your knowledge, we have created a quiz for you to try and name the 22 players to feature in that match.

Take the quiz.

There are debates about what is the biggest game in world sport but I would argue that is number one. You can make arguments about the football games but India vs Pakistan in cricket... it doesn't get any bigger. It will be the most watched sporting event with billions tuning in.

If they’re cheering that loudly just for winning the toss…

Pakistan captain Babar Azam: "We would have bowled first so we will try to get runs on the board and put pressure on them.

"We are confident, momentum and confidence are very high so we'll try to take that into this match.

"Jam-packed stadium so we'll enjoy this opportunity and try to give everything in this match.

"We need improvement in the field, to win these matches you have to field well. But we've had a couple of good practice sessions so hopefully we can do that."

India captain Rohit Sharma: "It cannot get bigger than this, no doubt about it. It is a fantastic atmosphere, you look for that and dream about it. We'll experience something really, really special.

"It looks like a good pitch and it shouldn't change too much and dew might be a factor in the second innings. With that in mind we thought it was better to chase.

"We don't to sit on laurels. We want to stride for our best and play a good game every game. It is a new start so we want to start well and play well.

"You've got to keep yourself relaxed and keep the team relaxed over the game.

"It is unfortunate that Ishan Kishan has to miss out. He has to step up when he's asked to and he's done that for us."

Pakistan's players are going to be up against 130,000 fans from India. It's going to be a hotbed. Sometimes that can go back on to the home team. Pakistan need to get off to a good start to win it. With the bat in hand they need to get that foundation. Most of them are in good form and playing nicely.

It's the Cricket World Cup, it's India v Pakistan and the atmosphere is already at fever pitch in Ahmedabad for one of the the most intense rivalries in sport.

132,000 people are expected at the Narendra Modi Stadium, all supporting India.

Strap yourselves in!
