Milen Lahchev (bg|Милен Лахчев; born 1 April 1987) is a former Bulgarian footballer and a current coach.
Lahchev began his youth career at Germanea, but later moved to Marek Dupnitsa. His professional years were spent mainly at Vidima-Rakovski and Lokomotiv Sofia, for whom he played in the UEFA Europa League.[1] Following brief stints at Montana and Romanian side Concordia, Lahchev returned to Marek in 2013, where he served as team captain.
In early 2017, without announcing that he is retiring as an active player, Lahchev, who holds a UEFA B Licence, left Marek to become head coach of Germanea.[2]
