Aston Villa and Nottingham Forest now know who they will face in the Europa League group phase, while Crystal Palace have discovered their fate in the Europa Conference League draw.
The Eagles were demoted to the Conference League following an intervention from UEFA owing to multi-club ownership rules despite winning the FA Cup last term, with Forest profiting from their misfortune.
Villa will face Fenerbahce but will not come up against Jose Mourinho, who was sacked prior to Thursday's draw. They will also host Bologna and RB Salzburg in the group phase with a trip to Feyenoord also pencilled in.
