Russia 2018: Joachim Löw and Germany's title defense

"Visionary, Spokesperson. Public relations manager."

These are what Joachim Löw sees as the prime roles of a national team coach. And he should know, he's been doing the job for 12 years now. That's nearly as long as Angela Merkel has been Germany's chancellor, which feels like an eternity.

Löw and his V-neck sweater have been around for so long that most Germans probably can't imagine an international football tournament without him, nor would they want to. And he has already signed a contract extension, which will keep him in the post through the end of the 2022 World Cup.

Why would he do that? Afterall, his list of achievements and honors is long. Löw is the coach of the World Cup champions, he has been awarded Germany's Federal Cross of Merit, he has been named FIFA Coach of the Year and his hometown (Schönau) has even named the local stadium after him. So what motivates him to carry on as coach of the national team when he has so much more to lose than to gain at the World Cup in Russia?

'Great potential in the team'

"The 2014 World Cup was a highlight for us all, but it was no the end of the story," the 58-year-old said recently.

One triumph is not enough for the Germany coach. He is aiming to do something that no country apart from Italy (in 1938) and Brazil (1962) has done before: to defend a World Cup title.

"Maintaining the highest level (of performance) requires a tremendous amount of effort," Löw told DW. "When you have a lot of success... you can sometimes lose the hunger, and that can play into the hands of others who are also ambitious and want to knock you off your pedestal. So the most difficult thing is to maintain this high level without falling off."

Löw believes in his squad, which he thinks has more talent than any other previous Germany team.

"I still see great potential in this team. It is still enjoy working with and further developing these players."

Löw also appreciates being in the position of being a popular national team coach, who isn't subject to the weekly pressure to deliver results that club coaches are. Apart from just before and during a European championship or a World Cup, Löw can work in peace and without much pressure from above, and he can focus on what he does best; developing mid- and long-term ideas, concepts and philosophies of play, as well as studying and analyzing upcoming opponents and general developments in football.

'We sometimes think about crazy things'

"We are always looking to be trendsetters, so we are always looking towards the future," Löw said. "We are visionaries in a way and sometimes we come up with completely crazy things. Even if they may seem absurd, we look to try them out at some point."

Could we see some crazy ideas at the World Cup in Russia?  Fans all over the world are wondering just how Germany will do, since the team's performances in it's last six internationals were anything but convincing. Prior to Friday's 2-1 victory over Saudi Arabia, Germany had lost to Austria and Brazil, after having played to draws against England, France and Spain - the last four of which are fellow contenders for the World Cup title. However, all this is no reason for worry, since Germany are a completely different team when it comes to major tournaments,  a team capable of delivering when it matters.

Sometimes it can all come down to luck

Löw prepared intensively for this World Cup for at least the past two years, and he believes that success should be left to as little chance as possible.  

"There is no success without planning," he said. "Clearly defined goals and consistent application can take you far."

That doesn't mean that Germany fans shouldn't be crossing their fingers, though.

"At the end of the day situations can still arise in which things come down to luck," Löw said.
