Mesut Ozil: Arsenal investigate coach Arber's Twitter bet claim

Arsenal have confirmed they are investigating "as a matter of urgency" whether academy coach Mark Arber bet on the signing of Mesut Ozil.
It has been reported that Arber, 35, posted a tweet on his personal account on Monday admitting he had bet on the German international midfielder's club-record £42.4m move from Real Madrid.
The Gunners will investigate a potential breach of gambling rules.
"We take this very seriously," said a club spokesman.
"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."
Football Association betting rules do not allow people to bet on any events involving their own club.
Arber played for Conference Premier side Dartford last season, having previously played for Peterborough, Barnet, Oldham and Stevenage
