Mikel Arteta longs for a killer instinct to go along with Arsenal's offensive aspirations.

At Old Trafford, there was excellent news for the all-conquering Arsenal team.

Not the Arteta Invincibles, who lost that label when their season-opening five-game winning streak was broken.

But the actual Invincibles, whose uniqueness spans eras.

Many previous Arsenal teams lacked that killer instinct.

That attacking prowess may have persuaded him to take a chance and frontload his side with a favourable triple change.

They have been criticised frequently for having elegance but not substance.

Although Arteta provided visual appeal, his harsh judgement made it clear that he is wanting both.
