Jens Lehmann has admitted that he is "very interested" in the possibility of keeping goal for Germany at the 2016 Paralympics in Brazil.
The shot-stopper retired from international duty after Euro 2008 and professional football in 2011, following a short stint at former club Arsenal, and was a columnist for Goal.com during Euro 2012.
However, in an interview with Bild on Monday, Lehmann spoke of his enthusiasm at making a sensational comeback in four years' time with his country's five-a-side blind football team.
"That's very interesting, providing I am fit to do so," the ex-Arsenal, Borussia Dortmund and AC Milan custodian revealed. "In any case, it's okay to talk about it if you are interested."
Paralympic rules stipulate that "all four outfield players must wear blackout eyeshades to ensure fairness. The goalkeeper may be fully sighted but he is not allowed to leave his penalty area."
Germany's five-a-side team failed to qualify for the Paralympics in London this year, but coach Ulrich Pfisterer was nonetheless enthused by the idea: "If Jens Lehmann joined, that would be sensational."
Friedhelm Julius Beucher, president of the Disabled Sports Association (DBS) in Germany, claimed that Lehmann's inclusion could pave the way towards other former goalkeepers representing disabled national sides.
"A goalkeeper is not subject to the requirement that he must have some kind of disability," he said.
"Thus, Jens Lehmann, Oliver Kahn or any other retired goalkeeper, in theory, is available. We will now discuss this privately."
Despite a successful playing career which saw him win league titles in England and Germany, Lehmann failed to mark any of his 61 Germany caps with a major honour.
