"There is a big difference with other sports, though. Understanding of the game and technique are vital in football and you cannot improve those areas by using doping.
"It's reassuring that you can play football at the highest level without the use of doping.
"I am all in favour of fair play and against cheating in any form. I would be perfectly fine with it if an anti-doping law would be put into place."
Lahm underwent six doping tests during Bayern's treble winning 2012-13 campaign, two of which were unannounced and conducted at his home.
