The really worrying thing about this for Arsenal, the thing that will have kept their supporters awake last night, is that Mikel Arteta’s team suddenly looked scared to win.
Teams play badly. Mistakes are made. Chances are missed. It happens all this time. But when teams play like Arsenal did here, just as they find themselves in sight of a glorious push through the finishing line, then it tends to hint at something deeper and more significant. It tends to hint at psychological weakness.
That’s a notion that Arteta’s players must dispel quickly and before it takes root.
