As far as I know, Aubameyang has not been able to transfer to a third team due to UEFA rules, as he has played for Barcelona and Chelsea this season. Under normal circumstances, he would be transferred to another team on loan for a season, rather than being confined to the bench. This season is a lost year for him. He is 33 years old and could get a chance to play one more season in Italy, Spain or Germany. Inter Milan could be a good opportunity for him to stay at the forefront of the European stage. Otherwise, we start talking about the Middle East or Far East possibilities for him.
That's only for one season. It's likely aubameyang will able to come back again to the barcelona in the summer transfer season. That's why aubameyang has been making some controversial to appear in barcelona's changing room. I don't even know what's his real motive but as a player and such attitude is really destroying his name. As a professional player and he can dislike the club but he must still show attitude towards the team that was still paying his weekly salary without any problem.
That's why he may be potentially terminated by chelsea at anytime. His attitude has represented his nature.
