The Gunners left-back was red-carded by Andre Mariner in a case of mistaken identity after Alex Oxlade-Chamberlain handballed Eden Hazard's shot on the goalline

I’ve seen some strange things at football matches but never anything like that. The whole press box was huddled around the TV screens trying to work out what actually happened during that penalty and red card incident.
It seemed like Andre Marriner missed the whole incident and listened to his assistant on the far side, who inexplicably identified Kieran Gibbs and not Alex Oxlade-Chamberlain as the man who handled.
Oxlade-Chamberlain told the referee 'it was me' but the protests fell on deaf ears. The most bizarre moment you will see all season.
However, the experienced official wrongly red-carded left-back Gibbs, believing the 24-year-old to be the guilty party.
Oxlade-Chamberlain seemed to own up to being the culprit but Mariner flashed the red card - his seventh in 22 matches, the most of all top flight officials - reducing the Gunners to 10 men.
Arsenal had already fallen two goals behind before Eden Hazard converted the spot-kick to put Jose Mourinho's side 3-0 up after 20 minutes in the highly anticipated clash at the top of the table.
Much of the build-up was centred on the landmark 1000th game of Arsene Wenger's tenure, with Arsenal requiring a positive result to keep pace with the Premier League leaders.
