If ONLY there was a way for him to change SOMETHING during this horrid stretch. The formation, the tactics, the players out on the pitch. Man, would be sweet if we weren't stuck with the same crappy players being hugely ineffective and largely uninterested whilst playing a 4-2-3-1.
That's why I put a bunch if this on Koeman himself. He's sticking with the same crap players making mistakes, not doing the basics, playing a formation that they don't allow any kind off coherence in and in a team they show 0 zeal for performing in. If something doesn't work, YOU CHANGE SOMETHING!
