Aston Villa's hopes of reaching the Europa Conference League final were hit by a chaotic semi-final first-leg home defeat to Olympiakos.
Ayoub El Kaabi scored a hat-trick, netting twice in the opening half hour as the Greek side took a 2-0 lead.
Ollie Watkins reduced the deficit for Unai Emery's side and Moussa Diaby equalised moments after the interval.
Olympiakos roared back in front with an El Kaabi penalty and a deflected strike from Santiago Hezze.
Douglas Luiz missed a late penalty, which means Villa must overturn a two-goal margin in the second leg in Piraeus on 9 May to reach their first European final since 1982.
