Arsenal train in Baku ahead of the Europa League final against Chelsea
Cech has started between the posts in every knockout match en route to the final in the Azerbaijan capital, but might still have to give way to German teammate Bernd Leno.
Midfielder Henrikh Mkhitaryan decided against travelling due to his native Armenia's dispute with Azerbaijan over the territory of Nagorno-Karabakh.
Arsenal will also be without Aaron Ramsey, Hector Bellerin and Rob Holding through injury, but Danny Welbeck has been included in the squad after sustaining a broken ankle last November.
