Clearly Arteta doesn't think he can trust Tierney as an inverted full back or the left centre half in the three and doesn't even see value in having an overlapping full back as an option on the bench. He has already used Timber and Tomiyasu ahead of him this season. If he isnt going to use him then there is little point in him staying and we wont be missing much.

However, I agree that this and losing Timber leaves us very short, shorter even than last season. I would like to think he will be bringing someone in before the deadline. We have finished the last two seasons down to the bare bones of our defensive cover and it has cost us both times. It will again if we do nothing.
