We all know Mikel Arteta isn't every Arsenal fan's favourite player, but this surely counts as going a bit too far.
The Spaniard has not been a first choice for the Gunners over the last year or so, largely due to injuries, but the club's official Twitter account made a bit of a booboo when announcing the teams for their match against Chelsea.
Arteta was included on the Chelsea subs bench - and if that wasn't enough, the club even tagged his Twitter handle so he'll have got a notification of the mistake.
Former Everton man Arteta is on Arsenal's bench, so he'll be looking to get the last laugh if he makes it onto the pitch.
