Ballack has flown out to South Africa to support his countrymen
Injured German captain Michael Ballack has predicted Germany will beat Argentina 3-1 in Saturday's World Cup quarter-final.
The 33-year-old midfielder, who was ruled out of the finals after injuring his right ankle in the FA Cup final in May, told German newspaper Bild he had no advice to give the young side.
"Everything is going really well, what they have achieved so far is fantastic," said Ballack.
"Under these conditions, we have our chances against Argentina and I predict a 3-1 victory."
Oliver Bierhoff says Germany will find it harder to beat Argentina in the World Cup quarter-final than they did to overcome England in the last 16.
Before the tournament began, England were rated more likely than Argentina to lift the coveted trophy.
But Germany general manager Bierhoff said: "It is not going to be easy on Saturday because Argentina are a stronger side than England.
"There were some obvious English weaknesses that had all been there in the group stages.
"Argentina are much more powerful and stronger. They have very few weaknesses - although there must be some."
German legend Franz Beckenbauer has called for the introduction of goal-line technology after Frank Lampard's effort was incorrectly disallowed during England's 4-1 defeat by Germany.
"I was sorry for England that Lampard's goal was not spotted," Beckenbauer told the South African Times.
"There is no comparison here to the famous Wembley goal scored by England in 1966 in the final against West Germany.
"Whether or not that shot from Geoff Hurst crossed the line is something you can still debate today, even if computer projections have shown that it wasn't a goal.
"That Lampard's shot landed behind the line is much clearer.
"I am pleased that the Fifa president wants to open the discussion again on perhaps using videos or microchip technology in the ball.
"There is also talk of additional match officials behind the goal.
"Whatever helps the cause of justice is also good for football. Just as long as it doesn't get too complicated."
Spain striker Fernando Llorente says the skin-tight shirt he wears when playing for the national team has helped his performance - because it makes him look like The Incredible Hulk.
The powerful 6ft 4in Spanish striker, earned widespread praise for his match-turning performance when he came on for Fernando Torres in the European champions' 1-0 over Portugal.
"Everyone was laughing because (the shirt) was very tight on me and I looked like Hulk," said 25-year-old Llorente.
"But I feel very comfortable with it and it also helps my physical performance."
One thing no one is laughing about is Spain's hopes of progressing to their first World Cup semi-final since 1950, when only 13 teams contested the tournament.
"We're in a situation where we can make history and we're part of a team that has no guarantees of getting back here," said Cesc Fabregas, "so we have to take advantage."
"Spain has already lived through enough lessons in its history at the World Cup and the Euros. Anything can happen, as we saw with Brazil."
According to a survey by Dutch bank ING, 40% of all workers in the Netherlands are taking the day off or working a shorter day in order to watch the national side's World Cup quarter-final match against Brazil on Friday.
The bank's survey of more than 86,000 people also forecast that local pubs will be 50% busier than they were for the country's second-round win over Slovakia.
Huh Jung-moo has resigned as coach of South Korea following their 2-1 defeat by Uruguay in the last 16 at the World Cup.
Under Huh Jung-moo the team advanced out of the group stage for the first time on foreign soil but the coach was eager to "recharge".
"There are many great and capable ... leaders in our football community. I think they should be given a chance to coach the national team," said Huh Jung-moo.
"What I felt during the World Cup tournament is that the global football powerhouses, especially the South American teams, performed well and were too much for us."
Former Argentina coaches Marcelo Bielsa and Jose Pekerman head Japan's wish-list to take over from Takeshi Okada, according to the Japanese press.
Okada is set to retire to a life of writing poetry and farming after the Blue Samurai were knocked out of the World Cup in the last 16.
"I want to get away from soccer," Okada told Japanese television following their penalty shootout loss to Paraguay.
"Even if I was offered a new contract. It won't happen so let's not talk about it."
Meanwhile, Japan defender Yuichi Komano is set to get a medal, even though his missed penalty against Paraguay led to the country's World Cup exit in the last 16.
The governor of Komano's native Wakayama prefecture, Yoshinobu Nisaka, told Japanese media he wanted to give Komano a medal for his efforts in South Africa.
"We would like to present Komano with a medal for giving people such dreams and emotions," said Nisaka.
New Zealand coach Ricki Herbert was guarded about his future when he arrived home on Friday after steering his team to an unbeaten World Cup campaign.
Although New Zealand failed to progress beyond the first round of the tournament, the team surpassed expectations.
Herbert is reported to have received approaches from clubs in Europe, Asia and the Middle East but would only say there were "a few things" in the air.
He said he was immediately returning to his job as coach of New Zealand's only professional team, the Wellington Phoenix, and expected to have talks about his future career with Football New Zealand.
