That was in reaction to Kahn's comments that there would never again be an era like his in which one goalkeeper is the dominant German number one.
With Lehmann's place in doubt after Manuel Almunia took his place at Arsenal, Kahn has taken the opportunity to have another swipe at the 37-year-old.
"Instead of showing no style in having a go at his former colleagues, he should be thankful that he even has the chance to play for the national team when he is not playing for his club," said Kahn in Thursday's Kicker magazine.
"This scenario has never arisen in the history of German football."
