What does Arsenal need before the transfer window closes?

“September’s coming soon; I’m pining for the moon,” Michael Stipe sings in R.E.M.’s "Nightswimming," the greatest track at the center of the elegiac masterpiece that is 1992’s Automatic for the People. Football has its own elegiac side, though the transfer market often appears concerned only with the present and future. Arsene Wenger, for instance, wants September because that will mean the end of the summer transfer window, enabling him to free himself from worries about Alexis Sanchez, his best player. Wenger has often appeared an unwilling participant in the transfer market, but he hasn’t survived for more than two decades by being a dreamer unable to live within the boundaries of the system.
