West Ham slipped to their first Europa League defeat of the season as they were beaten at Olympiakos.
Kostas Fortounis surged through the West Ham defence and struck from 25 yards to open the scoring.
Angelo Ogbonna then turned into his own net just before the break to further deflate the Irons.
Lucas Paqueta's brilliant volley in the 87th minute came too late with the Hammers unable to salvage something from the game.
David Moyes' side remain top of Group A despite losing.

Olympiakos started brightly, Sotiris Alexandropoulos' early effort forcing Alphonse Areola to save low down to his left.
The home side were winless in their past 11 Europa League games, their longest run without victory in major European competition, but there was no lack of confidence against West Ham.
The Hammers dominated possession but looked disjointed throughout, with Said Benrahma firing against the side-netting in the early stages.
James Ward-Prowse whipped a promising free-kick wide of the post, while Danny Ings got on the end of a corner but could not keep his header down and it nestled on the roof of the net.
More to follow.
