The context that matter is that the CB search has been an ongoing struggle for about 4 years at this point. We have repeatedly pulled this same stunt until ultimately settling for lesser options like Rodon and Lenglet.
So we should have come into this transfer window with a clear idea of who we want and the alternatives, and got a deal done asap. Among the big clubs in the PL, we are in an uniquely bad position the requires that level of extra effort.
Now it's hard for us to trust that Levy will have it sorted in a timely manner, hence the nerves from some quarters. I'm sure you'll note that I and others praised levy for getting the other tranfers done quickly, so it's not just being constantly negative.
As for not being on the plane. As I explained in an earlier post, the club has A LOT of other shit to do to get it from the horror show of last season to a proper team this season. Things like selling Winks or Sanchez can go on the back burner, but preparations for next season can't.
Consider the fact that Ndombele, Bissouma, Porro, and Spence are practically new players, and Vicario, Maddison, Solomon and Udogie are actually new players. With a new CB, that's essentially 9 new players in the squad for next season.
Ange has to transition us from years of defensive football culminating in total disarray, and to an attacking side while bringing together that many new players. It's not easy, look at chavski last season.
So with all that in mind, it's really inexcusable that this position hasn't been sorted.
