Argentina had been expected to ease past an unfancied Cameroon side in 1990
Argentina, led by Diego Maradona, were stunned as Francois Omam-Biyik's header saw Cameroon open the tournament with a 1-0 win over the favourites in Milan. An abiding memory of that game is Argentina forward Claudio Caniggia being taken out by Benjamin Massing's flying horizontal body check.

Former England captain Rio Ferdinand is backing home skipper Thiago Silva to lead Brazil to their sixth World Cup.
"For me, Brazil's Thiago Silva is the best centre-half in the world. I played against him when he was at AC Milan. Brazil are my tip for the title - they are playing at home, they are used to the conditions, they have a good defence and they have Neymar," says the ex-Manchester United defender on Match of the Day's preview show.

Nothing would bring the samba beat to a grinding halt faster than a Croatia victory over hosts Brazil. There have been bigger shocks on the opening day of World Cups past as well.
Back in 2002, defending champions France were humbled by former colony Senegal as El Hadji Diouf set up Papa Bouba Diop for the game's only goal.
Former England midfielder Paul Scholes urges Three Lions coach Roy Hodgson to put his faith in his younger players.
"There is no point taking people like Raheem Sterling or Ross Barkley to Brazil 'for the experience'," wrote the former England international in his blog for Paddy Power., external "Play them."
He added: "Some people might say it's risky. But these players have the fitness and ability to get the ball back if they lose it."

South American football expert Tim Vickery says Brazil is cutting some of its World Cup preparations "a bit fine", but is ready to host the tournament.
"The stadium in Sao Paulo has not been tested to its full capacity and will the airports be able to cope carrying the huge amount of passengers?" Vickery said on Match of the Day's preview show.
"We might also have one or two protests. However, there is a lot of enthusiasm, with the tickets sales very strong. You're beginning to feel the magic of the event. For Brazil in a World Cup - there are no half measures. The people who will be most nervous are the authorities if Brazil get off to a bad start. The nightmare for them is if Brazil get eliminated early."

"Early start at Rio airport for the flight to Manaus - and there is a vast Australian presence as they head for their opening game against Chile in Cuiaba.

"It has been a long build-up but the show is finally ready to hit the road."
Former England rugby union coach and one-time Southampton director of football Sir Clive Woodward believes that a draw against Italy in their opening World Cup group game on Saturday would be a failure by England.
"I hope Roy Hodgson banishes any thought of 'a draw will do'," he writes in the Daily Mail. , external
"Take risks, create the mindset: 'We must win'. Pick a team to score goals. Erase any negative thoughts about the heat and the jungle conditions and playing slowly. Let's surprise Italy, give them the unexpected, win the game before the opponents realise they are in a game."
One of the best things about a World Cup is that everyone, from your grandma to the Pope, shows an interest in the tournament. While you're not bothered about the former's opinion, the latter has taken to Twitter (yes, Pope Francis is on Twitter) to wish luck to all 32 teams.
"I wish everyone a wonderful World Cup, played in a spirit of true fraternity," tweets the leader of the Catholic Church.
Shouldn't Argentina-born Pope Francis be supporting Lionel Messi and the boys?
Former England captain Alan Shearer thinks Brazil and star man Neymar will thrive on the pressure of being the host nation.
"Neymar can take a lot of hope from how his team handled the pressure at the Confederations Cup last year," says Shearer on Match of the Day.
"He had a fantastic tournament - scoring four goals. I enjoyed the pressure at Euro '96 and I think Neymar and his team-mates enjoy the pressure too."

Spain's stars are known for using their heads. Their 2010 World Cup triumph, not to mention back-to-back European Championships, was based on intelligent football from the likes of Xavi and Andres Iniesta, not because the tika-taka masters like to lump the ball into the air. But if they do decide to go down the aerial route, then veteran coach Vicente Del Bosque can show them to keep possession using their foreheads.
