Arsenal and Chelsea both suffered shock defeats in Tuesday night’s Champions League action.
The Gunners now face an uphill struggle to qualify from Group F after they endured their second successive group loss at home to Greek side Olympiakos.
Manager Arsene Wenger now faces the real prospect of failing to reach the knockout stages for the first time in 16 years after they went down 3-2 at home to the Greek champions, following on from their matchday one defeat to Dinamo Zagreb.
Felipe Pardo’s effort took a nasty deflection off Alex Oxlade-Chamberlain to give the visitors a surprise lead on 33 minutes, but Arsenal replied immediately as Theo Walcott’s effort sneaked past the visiting goalkeeper just two minutes later.
Yet five minutes later home keeper David Ospina handed the lead back to the Greeks when he embarrassingly dropped the ball over his line from a corner.
Chilean forward Alexis Sanchez gave Arsenal hope when he headed home the equaliser on 65 minutes, however thoughts of a comeback soon dissipated as Icelandic striker Alfred Finnbogason, once of Edinburgh’s leading youth club Hutchison Vale, fired into the net less than a minute later.
Chelsea, meanwhile, took their poor domestic form into European action as they crashed to a 2-1 defeat in Portugal.
Jose Mourinho’s stuttering Chelsea side, who’ve won just two of their opening seven Barclays Premier League matches, went a goal down after 39 minutes to Porto, when Andre Andre converted from close range on 39 minutes.
The visitors responded quickly, however, and drew level courtesy of Brazilian midfielder’s Willian’s expert free-kick.
Counterpart Maicon restored the home side’s lead seven minutes into the second half to deepen the Stamford Bridge side’s woes.
Elsewhere, Barcelona came from behind at home to Bayer Leverkusen with two goals in the final ten minutes securing a 2-1 victory in Group E. German champions Bayern Munich crushed Croatian outfit Zagreb 5-0 to consolidate their place at the top of Arsenal’s group while Belarusian outfit BATE Borisov triumphed 3-2 at home to Roma in Group E. There was also victories for Dynamo Kiev, Valencia and Zenit.
