Aston Villa fell short of reaching their first European final in 42 years as Ayoub El Kaabi's double secured Olympiakos a 2-0 victory in their Conference League last-four second leg.
El Kaabi scored a hat-trick to help Olympiakos win the first leg 4-2 last week and he ended the tie with a remarkable five goals as the Greek side tied up a 6-2 aggregate victory.
Olympiakos will face Fiorentina - last season's runners-up - in the final in Athens on May 29, with manager Jose Luis Mendilibar coaching in his second successive European final after winning the Europa League with Sevilla last season.
Villa faced a daunting task in Piraeus as they tried to overturn the first-leg deficit and never truly looked like achieving it, with Unai Emery's side now winless in four games and seemingly running out of steam at just the wrong time amid a number of injuries.
