Unai Emery took his time in officially unveiling Granit Xhaka as the Gunners' skipper, only for the midfielder to be stripped of the armband this week.
Granit Xhaka was heavily booed during the match vs Crystal Palace and the Swiss midfielder reacted rather crudely.
"We are going to wait for the analysis tomorrow but, at the beginning, I think it's a small injury", Emery told a news conference.
Arsenal's faltering form continued as a much-changed side limped towards the last 32 of the Europa League with a 1-1 draw at Vitoria Guimaraes on Wednesday.
Arsenal bear begun laying the groundwork to rent a recent manager and held talks with Jose Mourinho closing week, in accordance to reports.
"I chose to give it to Aubameyang and everybody also agreed with that decision and now I am telling you he needs time to take that responsibility with confidence, but we give him that confidence, I give him that confidence".
10 killed in ongoing anti-gov't protests in Iraq
In a statement, he called on all sides to reject violence and said the Iraqi people deserve genuine accountability and justice. Prime Minister Adel Abdul Mahdi has received criticism for allowing security forces to try to repress protests strongly.
By the end of this season, Aubameyang would have just a single year left on his current contract, which could force Arsenal's hand if the club hasn't met, or at the very least is showing no signs of being able to meet, his personal ambitions on the pitch. "It happens. Teams have bad spells, they go through bad spells".
"I needed to take one decision, and now it is closed".
"We tried [to score] but also they are a very competitive team".
"Every player, we are going to support the four captains, and we are going to support him as our first captain because he has also made one extra step to achieve that responsibility".
Arsenal now sit fifth in the table - six points adrift of the top four - and Leicester could open up a nine point lead with victory at the King Power so it's vital we get a positive result to stay in touch.
"The gap is already six points to fourth and Arsenal are in a situation where they can realistically only afford to lose two more games this season to keep pace with the teams ahead of them", Paul Merson told Sky Sports.
