The draw for the Europa League third-round qualifiers was held in Nyon, Switzerland on Friday, with Italian club Sassuolo the only debutants this season.
West Ham, who move into the Olympic Stadium this coming season, will face the winner of the clash between Belarus outfit Shakhtyor Soligorsk and NK Domzale of Slovenia.
Hertha Berlin may have it tough as their potential opposition between Scottish side Hibernian or Danish giants Brondby may provide tricky away trips, while Ligue 1 duo Saint-Etienne and Lille will also have tough draws.
Les Verts will come up against AEK Athens and Los Dogues travel to either MTK Budapest or Qabala, who reached the group stage of the competition last season.
The third-round fixtures will be played between the dates of July 28 and August 4, with the second qualifying round ending on Wednesday and Thursday.
