The defender has posted an Instagram message following a disappointing end to his career in Europe
Bayern Munich captain Philipp Lahm described Tuesday's Champions League quarter-final exit at the hands of Real Madrid as a "bitter farewell" to the competition.
The holders secured a 4-2 win after extra-time at Santiago Bernabeu to seal a 6-3 aggregate triumph and a place in the semi-finals.
Bayern were on the wrong end of three controversial refereeing decisions, with Arturo Vidal given a second yellow card for what appeared to be a fair challenge, before Cristiano Ronaldo completed his hat-trick with two goals from offside positions in extra-time.
