Rudi Voller believes England and Belgium are capable of challenging a Germany team he feels is capable of becoming just the third nation to successfully defend the World Cup.
Germany remain the top-ranked side in the world having lifted the World Cup for the fourth time in 2014.
Asked if Germany could defend the title, Voller - who the World Cup as a player in 1990 and took them to the final in 2002 as a manager - replied: "Yes, of course. It'll be complicated, because except Brazil no one ever defended the title, maybe before the war Italy did, too, but only five teams participated back then.
"Generally speaking, it's very difficult, but four years ago before the World Cup in Brazil, no European team had ever won a World Cup title in South America.
"Our guys are definitely the big favourites, maybe with Spain and France, maybe England, who have a very good team, Belgium, but from the quarter-finals onwards, sometimes what's decisive is the daily form and then you'll see. But the possibility is given, that's for sure."
"He [Julian Brandt] has got a great chance [of making Germany's World Cup squad]," Voller added. "Independently from being part of the national team's last few games, he is part of the future of Germany and in the national team.
"There is a lot of competition in his position, but his progression is trending upwards, he is the future of the national team and I would wish for him and for all of us, that he'd take part and have a good World Cup."
