Arsenal drew Turkish side Fenerbahce, whose participation has been overshadowed by a domestic match-fixing scandal which could still see them expelled, while Schalke 04 face Metalist Kharkiv, who face a UEFA disciplinary hearing next week.

French side Olympique Lyonnais were given a tricky tie against Spain's Real Sociedad, while former champions Celtic of Scotland will face a long journey to Central Asia after they were drawn against the Kazakhstan champions Shakhter Karangandy.

Milan, who finished third in Serie A last season, were given the tie they probably dreaded most.

Massimiliano Allegri's team will not have played a competitive fixture before they visit the Netherlands for the first leg on Aug 20 or 21.

They could also be without forward Mario Balotelli, who limped out of a pre-season friendly against Los Angeles Galaxy on Wednesday with a thigh muscle problem.

Arsenal's opponents Fenerbahce, who knocked out Salzburg in the previous round, were banned from European competition for two years for match-fixing but reinstated pending an appeal at the Court of Arbitration for Sport (CAS).

The English Premiership side will travel to Istanbul for the first leg.

UEFA has not said what will happen if Fenerbahce beat Arsenal but then lost their case at CAS.

CAS has said it will announce its decision in the case "before August 28", the same week the second legs are due to be played.

Kharkiv face a UEFA disciplinary hearing on Tuesday. Last week, Metalist lost an appeal at CAS over a match manipulation case dating back to 2008.
