I think the most annoying thing is that the Havertz we see now has been there for all to see. Nobody can say that we couldn't have expected this transfer to turn out like this (if he doesn't somehow come good).
In fact, this transfer to that price was so unexpected that I thought Arteta must have seen something I haven't, he must have some kind of masterplan. But it seems like we're just getting the expected, the same Havertz who's been playing in this league for years.
