Should be three!

Cameroon are all at sea at the back as Croatia send in striker Mario Mandzukic right through the middle, he takes his time and comes under pressure from Nicolas Nkoulou, before slicing his shot wide with only Charles Itandje to beat. Bad miss.

A cracker!

He was the best player in the first half and Ivan Perisic scores a fine solo goal, which he makes look so easy. Cameroon goalkeeper Charles Itandje shanks his goal-kick straight to Perisic on the left wing, he controls it and then heads off down the wing, outpaces new man Dany Nounkeu and then smashes in left footed at the near post.

Game over?

Early opening for Croatia as Sammir barges his way through.

We are back in play in Manaus.

Change at the break for Cameroon, on comes Dany Nounkeu for Aurelien Chedjou.

Here come the sides for the second half...

John Bennett, BBC World Service:

"The shocking statistic is that Cameroon have only had one shot on target in 135 minutes of World Cup football.

"This side looks a pale imitation of the Cameroon side that thrilled the world with their attacking flair in 1990.

"Volker Finke will probably be thinking about bringing on Pierre Webo in the second half. Many Cameroon fans will be wondering why the Fenerbahce striker didn't start the game."

It's not often you put Rigobert Song and Zinedine Zidane in the same sentence, but Alex Song's uncle Rigobert is one of only two players to get two red cards at World Cups (along with Zidane).

Song was sent-off in 1994 against Brazil and then in 1998 against Chile.

In fact, since their first World Cup qualification in 1982, no country has received more red cards than Cameroon - they are on eight, level with Argentina.

Former Cardiff City manager Malky Mackay: "It's been interesting tactically, Cameroon started quickly but Croatia settled into being the better team. After the goal word came from the Cameroon bench to really press on but the sending off has caused them a massive problem.

"Cameroon can still attack and will be dangerous on the counter so Croatia will have to be clever if they are to go on and win this game now."

Half time and so far, so good for Croatia. The beers in Split are on Alex Song.

Segun Agbaje:, external Song is on a different level of stupid.

Des:, external Ah the old discrete elbow him in the spine manoeuvre. Good thinking Song.

Chris Mitchell:, external How utterly ludicrous from Alex Song. The definition of the term red mist. There didn't look like any provocation at all either.

Former Cardiff City manager Malky Mackay: "Petulance. Alexandre Song ran across Mario Mandzukic slighty as he was trying to get back and he strikes out at him. It's pathetic to be sent off for something like that.

"Now Cameroon have a mountain to climb, Song has really put his team up against it. Volker Finke the Cameroon manager looks perturbed. Niko Kovac, the Croatia manager, looks like he's just stepped off a catwalk. Cool as a cucumber."

So Cameroon need to win this one to stay in the World Cup and they are now down to 10 men. They are having a nightmare.

What are you doing Alex Song?! Pepe was guilty of a stupid red card for Portugal the other day but this is even worse.

Mario Mandzukic tussles with him off the ball and Song just punches him in the back!

Brainless. Referee Pedro Proenca has to show him a red card and Cameroon are down to 10.

Former Cardiff City manager Malky Mackay: "Cameroon are gambling now and it's quite early in the game to be doing that. The two centre-backs for Cameroon have got their work cut out because the two wing-backs Stephane M'Bia and Benoit Assou-Ekotto are just leaving them behind on every attack. And Croatia are the type of team who are very gifted playing on the counter."

Ivan Perisic looks a classy operator. He's the standout performer so far as Luka Modric and Ivan Rakitic are both being marked well by Cameroon.

Cameroon do put a neat move together and send Stephane Mbia away down the right but he takes so long to get a cross away that he gets shut down and wastes it.

Andrew: Cameroon are a hard-working side, but they're lacking some real standout individual talent. There's no one who looks like they are capable of taking this game by the scruff of the neck and dragging them back into contention. Unfortunately for Cameroon, the man who is capable of doing that is sitting on the bench nursing a knee injury. They are crying out for Samuel Eto'o here.

The tempo is way down now, you wouldn't know that Cameroon need a win. Croatia look very comfortable.

One punt downfield takes out the Cameroon backline, Ivica Olic races onto it and hammers a rising shot over the bar from wide on the left.
