Pierre-Emerick Aubameyang's weekend trip to Spain to watch El Clasico may have been the deciding factor in his departure from Chelsea.

The striker, who signed with Chelsea in the summer, has had a difficult few months since Thomas Tuchel, the manager who signed him, was fired and replaced by Graham Potter.

He was still playing for the club because of a FIFA rule that states players are only allowed to represent two clubs during a given season.

Although a gap in the law that might have allowed him to sign with MLS teams was discovered, the Gabonese man decided against joining LA Galaxy in February.

Chelsea could terminate Aubameyang's contract

As reported by Express, the former Arsenal striker's omission from the UEFA Champions League squad summed up his disastrous time at Chelsea, and he is yet to feature.

His recent trip to Spain and his appearance in Barcelona's dressing room has reportedly left the Chelsea's bosses furious and willing to terminate his contract in the summer so he can move on a free transfer, as reported by Goal.

He has played 18 times for the London club scoring three goals, one in the league against Crystal Palace and two in the Champions League against his former club AC Milan, which helped the Blues progress out of the group stage.

Auba plays mini-game in Milan

The 33-year-old looks unbothered by his current situation at the club and seems to be enjoying his £260,000 per week salary happily away from the team. As Sports Brief reported, Auba was spotted playing five-aside in Milan while wearing his Chelsea kit.

He uploaded the video on his Instagram story. The move appeared to show his nonchalance, but it was reported to have been a sanctioned break by the club for the out-of-favour striker, and he has not featured in the team since then.
