Lahm has not immediate plans to move into coaching but says he will continue to follow the progress of Munich - the club he first joined as an 11-year-old.
So with a combined 12 league titles, three Champions Leagues, eight domestic cups, two World Cups and two European Championships and 227 worldwide caps between them, it'll be interesting to see who tries to fill the boots of Lahm and Alonso over the next decade.
"I can't name a single particular moment, there have been so many".
"I'll remember my first league title, my first cup, the Champions League", he continued, "but I'll also remember the defeats - that's also part of football". "I'm a little sad to lose two such important players".
Lahm has prepared intensively for a life after football as he is shareholder of several companies producing care products and nutrition for athletes.
The 33-year-old will play his last game in the German Bundesliga on Saturday when Bayern face SC Freiburg, reports Xinhua news agency.
Although naturally a right-back, Lahm spent a large proportion of his early years at Bayern playing at left-back, and later on in his career, he was deployed as a defensive midfielder to screen the back four.More news: GE Appliances to get Google voice control option

So what now? Ever since Lahm announced he would be retiring, rumors have circulated regarding his future. "Standing on the training pitch every day and analyzing games in minute detail - I don't think that's for me".
"I can not imagine going back to Bayern, it will not happen, so there is no other option for me in Germany".
"But you never know what's going to come your way", he continued, philosophically.
"But obviously Bayern were sure of my qualities and did not sell me but took me back", Lahm remembered. We'll see about tomorrow.
Until then, there's just the small matter of one last journey to the ground, one last warm-up, one last round of applause from a sold-out Allianz Arena and, Bayern being Bayern, one last Bundesliga trophy to lift.
'I simply want to enjoy the whole day, ' he told a press conference ahead of the match.
