Germany basked in the glory of their fourth World Cup title on Monday after a nail-biting 1-0 victory against Argentina crowned them the first European team to win football's top tournament held in South America.

Bleary-eyed fans awoke after late-night street parties, fireworks and honking motorcades across the country, with ecstatic supporters singing 'Oh, it's beautiful!' and chanting 'Super Deutschland!' into the early hours.

Bayern Munich star Mario Goetze struck in the 113th minute of a gripping battle at Rio de Janeiro's Maracana Stadium as Argentina superstar Lionel Messi's hopes of emulating Diego Maradona ended in defeat.

"It's unbelievable what we have achieved. Whether we have the best individual player doesn't matter at all. You just need to have the best team," said delighted Germany captain Philipp Lahm.

Newspapers hailed "Super Mario" Goetze as the country's new "football god" and showered praise on the new national heroes, the first to win the title for a reunified Germany, who are due to be welcomed home Tuesday at Berlin's landmark Brandenburg Gate.

"It Is True", headlined Die Welt daily, with the three words printed in the national colours of black, red and gold. "What a match, what a fight, what drama."

Some 34.6 million Germans were glued to their screens to watch the game, an all-time record.

The German finance ministry said it would this week issue a special "World Champion 2014" stamp, of which it had optimistically printed five million before the final.

With four World Cups, the European powerhouses are now just one behind Brazil's record tally of five.

The tournament earlier saw Germany crush Brazil by a humiliating 7-1, and the hosts lost Saturday's game for third place 3-0 to the Netherlands, sealing the fate of national coach Luiz Felipe Scolari, whose contract Brazil's football confederation decided not to renew, according to local media reports.

Germany's win nonetheless sparked an explosion of joy in Brazil, which had been dreading the prospect of South American rivals Argentina winning the title on its territory.

"Thank God, thank God that Germany won," said Caio Ferraz, 45, a Brazilian looking up at the stars on Rio's Copacabana beach.

Argentines reacted with tears, cheers and violence after the dream of a third World Cup title slipped through their fingers, as clashes between hooligans and police ended a massive Buenos Aires street party.

Twitter said the game generated more than 32 million tweets worldwide -- more than 600,000 of them in the last minute. However, the figure was below the all-time record of 35.6 million tweets sent during the Brazil-Germany match.

The dramatic finale came after a month-long footballing carnival widely regarded as one of the most exciting World Cups ever.

Goetze's winner equalled the record tally for goals at a 32-team World Cup. The 171 goals from 64 games matched the number set in France in 1998.

Fittingly, Goetze's strike was another memorable effort in a tournament brimming with spectacular individual goals.

A gripping final before 74,738 spectators, which included German Chancellor Angela Merkel, looked destined for penalties after both sides had failed to break through stubborn defending with the scores deadlocked at 0-0.

But with just seven minutes of extra-time remaining, Andre Schuerrle burst clear down the left flank and crossed for Goetze.

The 22-year-old took the ball on his chest and then volleyed past Sergio Romero to spark delirium amongst Germans and Brazilians alike.

With seconds remaining Messi had the chance to conjure an equaliser, but a difficult free-kick sailed high over the bar.

It was a bitterly disappointing end to the tournament for Messi, who was named player of the tournament despite the loss.

But the prize was scant consolation for the 27-year-old four-time World Player of the Year, who had been keen to emulate Maradona by guiding Argentina to World Cup glory.

"The truth is it doesn't interest me at this moment," Messi said of the award.

"We wanted to win the World Cup for all the people in Argentina and we couldn't do it."

Argentina coach Alejandro Sabella was left ruing his team's missed chances as he reflected on a final defeat that mirrored the South Americans 1-0 loss to West Germany in 1990.

"They had more possession, but we had more cutting edge, more chances," lamented Sabella.

"When there are chances in a game that is so evenly balanced, you have to take them. We lacked a bit of efficiency."

Sabella, meanwhile, defended the contribution of Messi, who failed to conclusively end the debate surrounding his position in the pantheon of football's greats.

"It is a very demanding tournament and it drains everyone physically," Sabella said.

"He is already among the greatest of all time."

Messi's failure to add his tally of four goals in the first phase helped ensure that Colombia's James Rodriguez finished the tournament as top-scorer to win the Golden Boot with six goals.

Germany's Neuer won the Golden Glove award for the tournament's best goalkeeper.

The 28-year-old Bayern Munich player was presented with the award moments after the final whistle.

"It is unbelievable, and an awesome experience," said Neuer.

"Germany are world champions. I don't know how long we will celebrate, but we will go about it with big grins."
