The news that Johan Djourou has returned from the Swiss squad with injury perhaps couldn't come at a better time for us Gooners.
During the closed season we've watched as Kolo Toure departed for Man Citeh for a reported £15 million and Djourou's international team mate Phillipe Senderos has all but lined up a move to Everton, which is expected to be signed after the Gunners travel to Merseyside this weekend.
Of course we've brought in former Ajax skipper Thomas Vermaelen, but he's been on the sidelines virtually since he arrived and although Arsene Wenger says he'll be available for the trip to Goodison, his match fitness is already in doubt.
So with two departures (well, one definite and one pending) and two centre backs recovering from knocks, the only recognised player we have left in that position, presumably fully fit, is William Gallas. And let's face it, he wasn't exactly injury free last season. I'm discounting Mikael Silvestre quite simply because I no longer think he's up to being a top four Premier League player, while Alex Song may be a makeshift stand-in, but it's not his natural position and come January he could be required by Cameroon for the African Cup Of Nations In Angola.
If that isn't a cue for Le Boss to go out and spend a bit of cash, I don't know what is? But who should it be? Brede Hangeland? Neven Subotic? Matthew Upson? Serdar Tasci? Mamadou Sakho? Or some rough diamond we've never heard of and who'll send us scurrying to YouTube and Wikipedia for some kind of knowledge and reassurance that he's above the 6ft mark?
With less than 20 days to go until the transfer window slams shut, to be perfectly honest I'd be relieved if we signed anyone at the moment. And that's not as it should be with a club of Arsenal's stature.
Defence was our achilles heel last season and I thought that Le Boss had stated as much. But without a proven central partnership and with the new season just three days away, I'm beginning to relive the deja vu of the past few transfer windows - only this time I hope there will be something positive to write about before September 1.
