Mikel Arteta is under a blanket of pressure for the first time this season and has questions to answer after the Gunners dropped points twice in one week.
Although on its own, the 1-1 draw against Southampton and 2-0 loss to PSV Eindhoven make very little difference. They are still top of the table and in a commanding position to finish top of their Europa League group - the slight dip in results and performances has prompted concerns.
It is more born out of delay than genuine worry that Arsenal have fallen off. If Arsenal were five points back in the league and looking up, then these two games may have slipped under the radar. Such has been their unexpected ascent on the league table though, certain people have been waiting to be proved right and will jump at any chance.
