Last season, Pogba suffered a long injury and it could even be said that he almost missed a season. So, at the start of this season, Pogba returned with a handful of bad news, such as a doping case which could result in him receiving quite a heavy punishment and could sink his career. I think at this stage it is still an investigation stage where everyone is still waiting to see whether Pogba is really positive for doping or not. However, this incident was certainly very unexpected for Juventus fans and Juventus themselves seemed quite angry with what Pogba did. For this reason, let's just look at the final results of this ongoing investigation. Currently Pogba is being suspension and he must resolve this problem first before rejoining Juventus' main squad.
In fact, Paul Pogba career is adversely impacted by the ongoing doping scandal. A potential four year suspension might be disastrous for the French star if the accusations are found to be accurate. This suspension might actually be the end of his football career given his history of injuries. Additionally, his former team Juventus might feel differently about this situation. While it could be advantageous to avoid a potentially expensive contract their intentions might also be affected by Pogba uncertain future. In the end this circumstance highlights the precariousness of a professional athlete career particularly when confronted with both injuries and drug accusations.
