In his 126 minutes of World Cup action so far, Spain striker Diego Costa has failed to muster a single shot on target.

Brazil won their only previous fixture against Cameroon at a Fifa World Cup - 3-0 in San Francisco during the group stages of the 1994 tournament.

Midfielder Tim Cahill has scored five of Australia's 11 World Cup goals but is suspended for the final game.

Cameroon have had 30 shots in this World Cup but only three have been on target.

It's not easy being an international footballer, forced to stand in ice-cold water on a beautiful Brazilian day. Germany and Arsenal defender Per Mertesacker, external poses in an ice bath with team-mate Benedikt Howedes.

Netherlands coach Louis van Gaal says he expects goals galore when his side take on Chile.

Van Gaal said: "Chile are incredibly intense and very organised. They have a fantastic coach in Jorge Sampaoli who has convinced his players of the way to face games. It's beautiful to see them play.

"I predict a game with a lot of goalscoring chances, just as, like Spain, Chile is a team extremely anxious to attack."

South Korea coach Hong Myung-bo says errors were made in their preparation ahead of their defeat by Algeria.

The Asian side were beaten 4-2 by their Group H rivals and the manager said: "The result speaks for itself.

"We made mistakes in our preparation and during the match, but we need to look ahead now. There were lapses in concentration, particularly in defensive areas and we didn't play to our usual standard."

Abdulmalik Jr:, external Playing for your country is the most important. I remember when legends said Messi needs to win the World Cup to be great.

Jack Wiseman:, external Pride in playing for your country should far outweigh wages! Very disappointing that some players don't want to play for England!

Jon Murray:, external Country every time, you don't become a great without doing it on the biggest stage - sadly players just care about who pays them.

Croatia are in action today and they memorably finished third on their World Cup debut in France 1998, with striker Davor Suker scoring in each of the knockout games to finish as the tournament's top scorer with five goals.

They started their World Cup adventure with victories against Jamaica and Japan before losing to Argentina 1-0 with qualification already assured. In the last 16 Croatia saw off Romania before enjoying a stunning 3-0 win over Germany to reach the semi-final.

Eventual winners France ended their run but the likes of Suker, Igor Stimac, Slaven Bilic, Robert Prosinecki and Zvonimir Boban left the tournament with many admirers.

And such is Suker's standing in his home country, Croatia's all-time leading goalscorer can reduce grown men to weeping wrecks, as is evident in a video of the great striker meeting an overwhelmed fan.

USA coach Jurgen Klinsmann has claimed fixtures for the World Cup's group stages favour the more popular teams.

The Americans play Germany on Thursday, three days after their 2-2 draw with Portugal.

"We're already thinking about Germany," said the German. , external "We have one less day (than them) to recover. We played in the Amazon. They played in a place where you don't have to travel so much. Things are set up for the big teams to move on."

Australia will be going home soon, but do not be entirely surprised if they do so on the back of a win over the world champions - albeit the soon to be dethroned world champions.

Their performances against Chile and Netherlands were excellent even in defeat, and one player who caught the eye was 23-year-old Mathew Leckie.

Since 2011, the Melbourne-born forward has been developing his career in Germany, and recently signed for Bundesliga 2 side FC Ingolstadt for £600,000. His value will surely rise after this World Cup.

Mike in Derbyshire: Don't Premier League bosses realise that a successful national side enhances their product?

Ben in Gillingham: If I was a player, club would come first. Look at the likes of Lampard - scrutinised for every mistake he makes with an England shirt, yet loved and adored at Chelsea, no matter the performance. Again look at Terry, if he had missed an equally important penalty for England like he did in the Champions League final in 2008 do you think he would have been forgiven? No chance!

Alex Laing:, external I agree that international breaks are an annoyance. Premier League is what weekends are all about.

Marcus Copsey:, external David Beckham is a prime example of how English footballers should be. Would drop everything to play for England. Even friendlies.

John McEnerney:, external Club first - it pays your wages! Different for other sports where it's only possible to compete for your country. Clubs compete all year.

Henderson, 24, said he thought England's young players would learn from their World Cup experience, despite the disappointment.

He said: "We have a promising young side, hopefully we can gel together and in the future have many more happy memories.

"It doesn't really get much bigger than playing in the World Cup. It's been an unbelievable experience, but no matter whether we've had highs or lows, you have to learn from it as best you can. I'm sure the young lads here will learn from that and it will make them stronger and better as well."

Jordan Henderson says the spirit in the England camp is low but that now is the time for the squad to show a united front.

The Liverpool midfielder told the Football Association website:, external "It's not a great mood around the camp, but it's a time everyone needs to stick together, everyone needs to stay strong.

"I'm sure there will be days when you'll wake up and it'll come back into your head, but at the same time, what doesn't kill you makes you stronger and you have to keep going."

Which should come first - club or country? Here's what you've been saying on the BBC Sport Facebook, external page.

Pam Charles: Why would anyone want to play for England just to get abuse from the fans if results don't go our way? Pride in the shirt win, lose or draw has to work throughout the country, not just on the shoulders of those selected to play.

Nathan Kinnie Kynaston: If they're lucky enough to be offered a chance to represent their country, they should be over the moon with accepting the offer to help their country win!

Richy Hopkins: Surely your club is more important and playing for your country is a massive privilege, one that shouldn't be taken lightly.

The most tweeted game by far on Monday was the USA's 2-2 draw against Portugal, which sparked nearly eight million tweets. (7,997, 121 if you want to be precise.)

Clint Dempsey's goal, which put the USA 2-1 ahead with less than 10 minutes remaining, attracted 304, 603 tweets per minute. The next highest was Jermaine Jones's 64th-minute equaliser, which drew 234,956 tweets per minute.

Ticketless fans broke into the venue at both previous World Cup matches there, but there was no sign of such shenanigans during Belgium's 1-0 win.

Around 40 police officers lined up behind new fences at the specific part of the stadium where nearly 100 Chilean supporters forced their way in ahead of Wednesday's Spain-Chile game.

A special contingent of 600 police, some carrying assault weapons, began blocking off streets and setting up barricades around the Rio de Janeiro stadium before dawn and police were checking fans' tickets as they left the train station to make the short walk to the game.

Australia defender Ivan Franjic says the Socceroos are aiming to pile more misery on 2010 World Cup winners Spain.

The two teams - both already eliminated - meet in Group B tonight searching for their first points of the tournament.

Franjic, 26, told Professional Footballers Australia:, external "Spain is a world-class nation. They have been dominating games but just not scoring goals, but I think with the boys' confidence from the last two games means we could win this game and finish the tournament on a high note."

Luke Shaw is due to make his World Cup debut when England take on Costa Rica on Wednesday. The 18-year-old full-back will become the fourth-youngest player to represent England at a major tournament, behind Michael Owen, Wayne Rooney and Alex Oxlade-Chamberlain.

Vinny Person:, external Playing football for England has become an unnecessary obligation, a favour and a chore and that's partly thanks to the FA.

Rob Meech:, external Country should come first. But the astronomical wages paid in the Premier League by clubs means it's no surprise if it's not.

Nick Pashley:, external Could England beat any Premier League team these days?

Xabi Alonso refused to be drawn on suggestions that his team-mates were irked by his comments that Spain lacked hunger, and insisted the atmosphere among the squad in Brazil was similar to during the triumphant Euro 2012 campaign.

"I'm not going to say what's happening in the dressing room - for me that should stay there," he said. "The atmosphere and feeling in the dressing room is the same as it was two years ago. It's all very natural; there isn't the tension that you (the media) imagine there is.

"We know that we lacked intensity, but our enthusiasm has been the same as always. The hardest thing was (to repeat) what we have already done, which is to win three competitions in four years."
