You simply cannot argue with Cameroon's official slogan at this World Cup; 'A lion is always a lion.'

Spot on. Whether they are still indomitable or not is open to interpretation though.

Alex Song on the right wing? That really will be worth staying up for.

Cameroon or Croatia then? Rakitic or Song?

The French World Cup winner gave answers your questions including:

Were Spain over-confident?

What do England have to do to beat Uruguay?

What do you make of Raheem Sterling?

Almost anthems time. The 22 players are in the tunnel in Manaus. Notoriously hot and humid of course...

Croatia's last victory in the World Cup was a 2-1 victory over Italy during the 2002 finals in Japan. Ivica Olic scored the first Croatian goal that night and he starts again this evening.

Great longevity. Can he do it again? He was a menace during Croatia's defeat to Brazil.

BBC World Service reporter John Bennett in Brazil:

"The injury to Samuel Eto'o has given Cameroon's brightest young talent a chance to show what he can do on the big stage. 22 year-old Vincent Aboubakar was the third-highest scorer in the top flight of French football last season, finding the net 16 times for Lorient.

"With Eto'o reaching the end of his illustrious career Cameroon fans are hoping Aboubakar can be his successor. We'll find out just how good he is tonight."

Alex Song and Eduardo - foes tonight but former Arsenal team-mates - leave the field after their warm-up arm in arm.

Who will come out on top tonight?

Croatia midfielder Ivan Rakitic starts tonight, he's already had a good week.

The 26-year-old has joined Barcelona on a five-year contract from La Liga rivals Sevilla.

Swiss-born Rakitic, who has won 62 caps for Croatia, joined Sevilla from German side Schalke in January 2011. He made 149 appearances for the club, scoring 32 goals.

We will be bringing you full live commentary as normal once we get closer to kick-off, but for the moment our attention is on the big news of the night - the elimination of Spain.

Samuel Eto'o waves to the crowd as Cameroon warm up but the talismanic number nine is not playing tonight.

He's injured and could be a major loss.

Estadio Amazonia, Manaus

Capacity: 42,374

Opened: March 2014.

Altitude: 72m (236ft)

Climate: Difficult. Tropical heat with tropical storms. Highs are a toasty 30C with a 40% chance of thunderstorms in June, with humidity up to 80%. Expect to see plenty of drinks breaks.

Time Zone: GMT -4 hours.

Approximate distance from Rio: 2,659 miles.

Where is it?: The capital of the state of Amazonas, Manaus is the furthest north of the host cities.

Fixtures: 14 June, England 1-2 Italy 18 June, Cameroon v Croatia, 23:00; 22 June, United States v Portugal, 23:00; 25 June, Honduras v Switzerland, 21:00.

Background: The arena has an elaborate steel structure, imported from Portugal, which envelops the playing area like an indigenous woven basket. Over 95% of the material from the old, demolished, stadium will be reused.

This was arguably the most complicated construction project undertaken for the World Cup, in part due to the climate but also because of the location. An urban island in the heart of the rainforest, Manaus is very hard to reach by vehicle, so most materials arrived by plane or ship.

Construction was overshadowed by the deaths of three workers in accidents. Two were killed in separate falls in March and November 2013, while another died in February 2014 following an accident involving the dismantling of a crane. A fourth worker died of a heart attack on site last year.

No room for error.

Croatia and Cameroon both lost their opening games in Group A and face each other tonight knowing that a second defeat will spell curtains to their chances.

The losers can book their seats home. The winners could still make the last 16. Who wants it?

Cameroon captain Samuel Eto'o is nursing a knee problem and is left out of the starting line-up. Vincent Aboubakar replaces him.

Croatia forward Mario Mandzukic starts after serving a one-match ban against Brazil, with Nikica Jelavic making way. Luka Modric overcomes a foot injury sustained in the opening game.

Cameroon: Itandje, Assou-Ekotto, Nkoulou, Song, Moukandjo, Aboubakar, Choupo Moting, Chedjou, Mbia, Enoh, Matip.

Croatia: Pletikosa, Pranjic, Perisic, Corluka, Lovren, Rakitic, Modric, Srna, Mandzukic, Olic, Sammir.
