It was yet another dreadful night for English teams in UEFA Champions League as Arsenal slump at home to Olympiakos while Chelsea crash away to FC Porto at Estadio do Dragao.
Olympiakos who had not won in their previous 12 outings against English opposition romped into a 3-2 maiden victory at Emirates to condemn Arsenal to their second consecutive champions league loss having succumbed to a 2-1 defeat away to Dinamo Zagreb a fortnight a go.
Felipe Pardo put the visitors 1-0 up in the 32nd minute, but Theo Walcott pulled a leveller two minutes later before David Ospina’s own goal restore the advantage for Olympiakos as they head to half-time.
Alexis Sunchez drew the Gunners level five minute after the hour mark, but Alfred Finnbogason tapped in to restore Olympiakos’ 3-2 lead imediately as the Greek sides held on to claim the famous triumph.
Elsewhere, Jose Mourinho’s return to FC Porto since he left in 2004 only added to his undoing as he watched his sides stunned 2-1.
Ruben Maicon and Andre Andre strikes in either half cancelled out Willians’ curling free kick to extend further Chelsea woes.
Meanwhile, Bayern Munich put five past Dinamo Zagreb who shocked Arsenal two weeks a go in group G opener.
Barcelona came from a goal behind to beat Bayer Leverkusen 2-1, while BATE Borisov eased past Roma 3-2.
