Germany head coach Joachim Loew says he knows the areas where the defending champions must improve before the World Cup after drawing 1-1 with Spain.
Rodrigo Moreno put Spain ahead after just six minutes in Duesseldorf, but hosts Germany levelled when Thomas Mueller hit a superb equaliser in his 90th international.
"There was a good intensity to the game, it was a test in which we were able to learn a lot," said Loew.
"Both teams have room to improve and you do not always want to show everything so soon before a World Cup."
"Both teams will have more to show by the time the World Cup comes around."
"We're at a good level, but we can still play better, especially in defence where we allowed the Spanish too much room."
