He could now be set to leave the club in January.
Pierre Emerick Aubameyang has been stripped of the Arsenal captaincy.
The Gabon striker was left out of the win at Southampton last weekend for a 'disciplinary breach' and won't be involved against West Ham United tomorrow.
Aubameyang scored 22 Premier League goals in each of his first two full seasons as an Arsenal player, but has netted only four times in this campaign.
There is speculation now that he could be set for a move in the January transfer window if his relationship with Gunners manager Mikel Arteta has broken down.
A statement on Arsenal.com reads:
Following his latest disciplinary breach last week, Pierre-Emerick Aubameyang will no longer be our club captain, and will not be considered for selection for Wednesday's match against West Ham United.
We expect all our players, particularly our captain, to work to the rules and standards we have all set and agreed.
We are fully focused on tomorrow’s match.
