Paul Pogba’s return to football has suffered another setback after the French midfielder picked up a fresh injury during training with AS Monaco. Pogba reportedly left Tuesday’s training session in pain and will now undergo medical tests to determine the extent of the injury. Pogba has already had to fight his way back from a doping suspension and a series of fitness problems that disrupted his career. That makes this latest injury particularly frustrating for a player who has already endured a long road back. For Monaco, the immediate priority will be to establish the seriousness of the problem before deciding on the next step.
