A Dinamo Zagreb player who tested positive for drugs after a Champions League win against Arsenal has been banned from football for 4 years.

Arijan Ademi came back positive for a banned substance following their 2-1 victory over the Londoners in Croatia in September.

The Macedonia international insists he is not guilty but has been punished by UEFA.

Arsenal manager Arsene Wenger has really spoken about the issue of doping in football, suggesting that he had "played against many teams" who may have been doping.
