Dinamo Zagreb have confirmed midfielder Arijan Ademi failed a doping test in the aftermath of the club’s Champions League group stage victory over Arsenal.
The 24-year-old played the whole 90 minutes of the 2-1 win on September 16 but could now face a lengthy suspension as he awaits the result of a B sample.
A statement from the club read: “We are aware of the results of the doping control test after the Champions League first round match against Arsenal.
“Our player, Arijan Ademi, tested positive, and Uefa has opened proceedings against him.
“According to Uefa rules, Dinamo cannot comment on the case until the B sample is given.
“For years, our players have been regularly subjected to doping controls and nothing like this has ever happened, so we have to say that we are surprised by the result.
“Arijan Ademi was tested six times last year and each time the result was negative. Players have also been tested several times this season by Uefa and the Croatian Anti-Doping Agency and everyone was always negative.”
The repercussions of the player’s violation are yet to be made official by Uefa, though the governing body’s anti-doping regulations state that the player could face a minimum of a two-year suspension, while the club are likely to avoid punishment unless more than one player is found guilty of substance abuse.
