Dinamo Zagreb says midfielder Arijan Ademi failed a doping test after the Croatian side's Champions League win over Arsenal last month.

Ademi played the full 90 minutes of Dinamo's 2-1 home victory in the Group F match on Sept. 16.

In a statement on its website, the club said Wednesday that; "Due to a positive doping test after the Champions league match Dinamo - Arsenal, UEFA instigates disciplinary proceedings against Ademi."

The club said it was "surprised because Ademi was selected for doping control six times this year and results were negative every time, as well as results of every other player who was selected for doping control by UEFA or Croatian Anti-Doping Agency."

Though he played for Croatia at youth level, the 24-year-old Ademi is a Macedonia international.
