Benitez had full automony over every signing this window and ultimately did choose not to sign a full-back. Now where Brands comes in is that clearly the targets he lined up weren't, in Benitez's mind, worth it.
Benitez wasn't convinced on Dumfries. We probably never had the money for it once Inter came in but Brands had worked on the deal (led to believe Dumfries had even agreed personal terms) - would have been a loan to buy.
Benitez didn't want to spend so much on Patterson (£10m+) - again, I can't blame him. Benitez didn't want anything but a loan for AMN.
