Hertha BSC are keen to take Arsenal youngster Serge Gnabry on loan, according to sources of German newspaper 'B.Z.'. The 21-year-old midfielder, who scored at the Olympics in Brazil five goals in the matches of the group stage, is believed to be Berlin's alternative to Alexander Esswein. The capital club is interested in the winger from FC Augsburg for weeks, but they still couldn't get an agreement about the transfer fee. Talks between Hertha manager Michael Preetz, Gnabry's agent and the Gunners are said to have started.
