Germany must improve in both defence and attack if they are to overcome France in Friday's quarter-final, say former captains Oliver Kahn and Lothar Matthaeus.
"The mixture is not ideal at the moment," said Kahn, who captained Germany to their 2002 World Cup final defeat to Brazil. "There needs to be a better balance between the forwards and the creative players like Mesut Ozil.
Matthaeus said Germany's problems begin in defence as centre-backs Benedikt Hoewedes and Jerome Boateng have been used mainly as wing backs at the World Cup.
"If you play in an unfamiliar position, you lack rhythm and can't produce a top performance. That was a big problem against Algeria," said the 53-year-old, who won the trophy in 1990.
