The Gunners goalkeeper knocked the ball over his own line to restore the visitors’ lead as Arsene Wenger’s men lost a second Champions League game in a row
Substitute Alfred Finnbogason was the match-winner for Olympiacos as his strike condemned Arsenal to a 3-2 defeat at the Emirates Stadium in the Champions League on Tuesday.
Arsene Wenger’s side remain pointless in Group F as they had nothing to show for their efforts despite twice equalising as suspect defending and a calamitous David Ospina error helped ensure Olympiacos their first win on English soil.
Theo Walcott was picked to replace the suspended Olivier Giroud and the England international looked to have ensured Arsenal parity at the break, having cancelled out Felipe Pardo’s 33rd-minute opener.
However, Ospina inexplicably dropped Kostas Fortounis’ corner behind the line five minutes before half-time – the goalkeeper having been selected ahead of regular number one Petr Cech.
Walcott turned provider for Alexis Sanchez to equalise for a second time shortly after the hour but Arsenal were again caught flat-footed as the visitors broke from kick-off – Finnbogason making his impact off the bench with a well-taken finish from close range.
It leaves Arsenal’s hopes of progression looking gloomy, while the severity of the injury that forced Laurent Koscielny off could add further frustration for Wenger – who will face difficult questions on his goalkeeping selection on the eve of the 19th anniversary of his appointment in north London.
