Academy coach Mark Arber reportedly admitted in a Tweet that he bet Arsenal would sign Ozil.
Arsenal academy coach and former football league defender Mark Arber, 35, could face disciplinary action over claims he posted a message to his Twitter followers that imply he benefited from placing a bet over the deadline day arrival of former Real Madrid playmaker Mesut Ozil, 24.
'Lovely bit of 14-1,' PA Sport quote Arber to have said on his @1Arbs social network account.
If Arber used sensitive information obtained from his position as a club insider as a means to manipulate bookmakers then he may be subject to more than the imminent club probe as official FA rules dictate that: 'You are not allowed to place a bet on a game or competition in which you have any influence, either direct or indirect.
'The above includes all bets related to the following: Any other events involving your club or other clubs playing in the same league competition [such as next manager markets].'
There is currently no response on the official Arsenal website, however, one club spokesperson did inform BBC Sport that they are treating the matter with the utmost urgency.
'We take this very seriously. All Arsenal employees and workers are well aware of their responsibilities in this respect and we are looking into this as a matter of urgency.'
Arber's Twitter account is currently set to private.
