The Football Association has reportedly approached Arsenal manager Arsene Wenger to elaborate on his recent claims that there is a doping problem in football.
The Frenchman revealed in an interview with L'Equipe that he has encountered "many teams" that have used performance-enhancing drugs.
One particular incident came to light in September when Arijan Ademi failed a drugs test following his side's 2-1 win over Arsenal in the Champions League.
According to the London Evening Standard, the FA has contacted Wenger, asking him to have a discussion about his doping concerns and provide any information that he may have.
The English governing body is taking the claims seriously, but Wenger is not in any trouble.
