Due to Antar's performances during the 2002 FIFA World Cup qualifiers in 2001, Lebanon's national team coach, Theo Bücker, had assisted him in a transfer to Bundesliga outfit Hamburger SV, on loan from Lebanese Premier League club Tadamon Sour [REF].
During his two-year stay with the club, Hamburg would claim the 2003 German League Cup, however, after failing to establish himself with the north German side (after he played in the Regionalliga Nord for Hamburg's reserve side for the 2002-03 season), he opted for a free-transfer to SC Freiburg [REF].
