Oliver Kahn has told Lehmann that he should retire in the wake of his recent escapades.
After Lehmann stole the wrong headlines this week, first for criticising his club and then for storming off at the end of their 1-1 draw with Mainz after receiving a red card and giving away a penalty, Kahn has advised him to bring the curtain down on his career now.
"Maybe it would be better for him to retire now," Kahn told the Az newspaper. "Who knows where things might yet lead.
"Jens is a good goalkeeper, but what should the management (at Stuttgart) think?
"There is no point to it anymore. Stuttgart's management have got to work out whether Lehmann is helping or damaging the team."
