Paul Pogba’s backup B sample also tested positive for testosterone, meaning the Juventus midfielder now faces a doping investigation.
The tests were carried out by Italy’s anti-doping agency Nado Italia, which provisionally suspended Pogba almost a month ago after a positive test following Juventus’ game at Udinese. 20. Pogba did not play a match in Serie A but was on the bench for Juve.
Pogba remains provisionally suspended and faces a ban of up to four years.
Neither Pogba nor Juventus have publicly contested the test results.
“Humanly, I feel sorry for Paul,” Juventus coach Massimiliano Allegri said on Friday.
The doping case is another negative note for a player who has been plagued by injuries since joining Juventus from Manchester United more than a year ago.
A knee injury ruled him out of France’s run to the World Cup finals last year and played just six Serie A matches for Juventus last season.
A police investigation is also underway in France into allegations Pogba was targeted by extortionists – including his older brother Mathias, who has denied any wrongdoing.
