Ibrahimovic skipped training at PSG yesterday.
A club spokesman told L'Equipe that Ibrahimovic was following an adapted, personal regime and doing his own work in the gym.
Although there may not be any evident breakdown of the relationship between Ibrahimovic and PSG, relations have shown signs of deterioration in recent weeks.
According to reports in France, the pony-tailed star was left enraged last month by PSG staff after he was refused permission to park in the club’s car park which is reserved for technical staff.
As a response to the refusal by the on-duty car-park wardens, the Swede instead decided to park his car at the entrance to the technical staff car park, therefore blocking all other vehicles from entering and leaving the complex.
