Pogba Faces Multi-Year Ban After Failed Doping Tests

Pogba tested positive for a banned substance in an anti-doping test in August.
Backup samples have confirmed the presence of the prohibited substance.
The substance was initially reported as testosterone but later identified as DHEA.
Pogba faces a potential 2-4 year ban pending investigation and appeals.
The failed tests cast further doubt on Pogba's injury-plagued second stint at Juventus.
