Arsenal under arsene wenger always play average , no matter they have signed a new classy player such as petr cech , alexis sanchez etc they keep playing ordinary, nothing special can make them favorited to be a champion of premier league.
Well thery were the runner up for premier league last season, if you think that it is not good enough then you are definitely sick. Without wenger, arsenal could be worse and instead of trying to sigh new coach, arsenal should stick with wenger and use the funds to sign some young players, that could be better for them
