Napoli will face Athletic Bilbao, Lille, Copenhagen, Standard Liege or Besiktas in the Champions League preliminary round.
Today’s results have whittled down the challengers for Friday’s draw.
Zenit fought back from a first leg defeat against AEL to win 3-1 on aggregate, pushing Athletic Bilbao into the next group of seeds.
The biggest danger in the draw is Athletic Bilbao, who finished fourth in La Liga last season.
Other options are Lille, Copenhagen – who caused Juventus many problems last term – Belgians Standard Liege and Turkish club Besiktas.
The preliminary round will be played on August 19-20 and 26-27.
