Villa and Ajax learn European fates as play-off draws made
Ajax will face either Astana of Kazakhstan or Ludogorets of Bulgaria as they kick off their Europa League campaign later in August.
The Dutch giants missed out on a place in the Champions League last season and will have to endure a long and gruelling journey in Europe's secondary competition if they are to make the final in Dublin next year.
Maurice Steijn's side won the Europa League in 1992 but have not started the season in the tournament since 2009.
Premier League pair Liverpool and Brighton will not feature until the group stages alongside Europa Conference League winners West Ham and several other teams from Europe's top leagues.
Meanwhile, Greek champions AEK Athens will have to overcome Dinamo Zagreb to set up a play-off round tie with Copenhagen or Sparta Prague.
Scottish side Aberdeen will also feature and they await the winner of Zalgiris Vilnius vs Hacken.
