Nicknamed
PAF after his initials, Frau was born on 15 April 1980 in
Montbéliard, France, where he became a young find of his hometown club
FC Sochaux-Montbéliard, and it was there he got his first opportunity to play in the France national league. After completing what would have been a prospective move to Lyon from Montbéliard, he found his playing time in the 2004–05 season hampered by the presence of other established frontmen like
Sylvain Wiltord,
Nilmar and later,
John Carew. Realising that it was a
World Cup year with a slim chance to catch the attention of national coach
Raymond Domenech, Frau secured a half-season loan to
RC Lens, but failed to make the cut to the final
France squad. Frau was called up to the senior
France squad by Raymond Domenech in August 2004 but did not make it off the bench. For the following season, RC Lens wanted to keep him in
Lens, but Frau preferred a move to
Paris Saint-Germain. The transfer fee was not disclosed, but Olympique Lyonnais priced the striker at £4 million. On 1 January 2008, Frau signed a three-and-a-half-year deal with
Lille and was given the shirt number 17. Frau is known as one of the more famous players at his hometown club FC Sochaux-Montbéliard. ==Honors==
