In the summer, Pierre-Emerick was the victim of a violent robbery at his home.
A broken jaw was the result of an altercation at his home near Barcelona, just before he joined the Spanish club.
Potter said he has been impressed with the former player.
Potter said that he wouldn't be a human if it wasn't affecting him.
The best thing for him to do is to play football, to put the incident behind him, and to be happy. He feels that here. I have been very impressed with him.
It was horrible to say the least. The family are concerned about something that you are talking about.
I can only do what he does and he has been perfect.
"The feeling that we are no longer safe in our own home is hard to understand and describe, but as a result of the violent cowards who broke into my home," said the player.
Potter is looking to get his first win in the European competition after a draw with Red Bull Salzburg in the group stage. The opening match of this season's competition was lost by the Blues by a score of 2-0.
