Arsenal tabled offers for three defenders in the closing stages of the summer transfer window and was snubbed at every turn in his last-ditch efforts to sign a centre-back, which means he must now rotate just three players in that position until January at the very least.
Gunners boss Arsene Wenger asked Manchester City if they were willing to part with Matija Nastasic as part of his frantic search for a centre-back on transfer deadline day, although according to The Telegraph that inquiry was swiftly rebuffed.
Triple transfer snub
Wenger also failed in his efforts to stop Kostas Manolas joining Roma last week, while Borussia Dortmund's £16 million asking price for his countrymen Soktaris Papastathopoulos proved too steep.
Premier League stalwarts in Aston Villa linchpin Ron Vlaar and West Ham stopper Winston Reid were much further down the pecking order, but regardless Arsenal will now have to nurse Laurent Koscielny, Per Mertesacker and Calum Chambers through the next four months of fighting for success in three competitions.
Koscielny must be Arsene's main concern
Wenger's failure to sign a centre-back to replace former club captain Thomas Vermaelen when you consider Koscielny's niggling injury worries, which include a long-standing achilles complaint.
The Gunners have so far managed to nurse Koscielny through the first month of the season without major issues, but that's only due to the meteoric rise of Chambers.
The 19-year-old has shown calm and composure beyond his years during his first few senior matches as a centre-back, but injuries to either Chambers or Per Mertresacker and Arsenal are surely in big trouble.
Wenger even let Miquel move on
Arsenal have also allowed one of only four recognised centre-backs on their books to leave on loan in Ignasi Miquel, with the Spanish youngster set to spend another season on loan in the Championship with Norwich City.
Miquel lacks experience but simply would have been another body at centre-back until the January window opens, but it seems like in an emergency situation Wenger would be happy to let Nacho Monreal move inside to cover.
Gunners fans will be probably left very disappointed with that stance but that's what Wenger has been left with after some deadline-day woe in terms of chasing suitable defenders, for better or worse.
