The Gunners bounced back from their 2-0 defeat to West Ham United at the Emirates Stadium on the opening weekend of the new season with a 2-1 victory over Palace at Selhurst Park.
Arsene Wenger’s side took the lead as early as the 16th minute through Olivier Giroud, but Joel Ward's driven shot drew Palace level just before the half-hour mark.
Arsenal had the last laugh, though, as Damian Delaney sliced an Alexis Sanchez header into his own net on 55 minutes.
The overall performance of the North London outfit left much to be desired, and Le Saux has highlighted what he considers to be a big concern for Arsenal fans.
The big concern if you're an #ARS fan now is that nobody is playing the disciplined holding midfield role. No protection in front of CB's— Graeme Le Saux (@graemelesaux14) August 16, 2015
Francis Coquelin is the first-choice defensive midfielder for Arsenal, but he was far from his best against Palace.
The Frenchman was erratic in his decisions and committed far too many fouls that he should have (four).
In fact, the 24-year-old was shown a yellow card and was lucky not to be sent off before being substituted in the 64th minute.
While Coquelin remains a good player, the match against Palace highlighted the need for Arsenal to buy a world-class defensive midfielder who knows how to get the job done no matter what.
