I'm afraid you're mistaken, again, and its becoming extremely difficult to take seriously your claims to have any real knowledge about Bilbao or Herrera. Herrera was the right sided centre midfielder in Bielsa's system, however Valverde used him as a #10 in a 4-2-3-1. Anyone who watched Bilbao last season would have seen this. In fact Spanish football experts, such as Graham Hunter, say Herrera's early season struggles were down to him learning how to play as a #10 (

I'm not going to continue debating with you about Herrera' position. Based on the incorrect claims you've made about Ander, I simply can't believe that you know him as a player like you say you do. If I'm honest, you're coming across as a guy who saw some stats about passing completion on a webpage and decided to set yourself up as an Ander Herrera expert. For example, you talk about Herrera not knowing when to play the killer ball. The image below, courtesy of Sky Sports (
link), shows in 2013/14 Herrera played as many successful through balls as Iniesta though. I take it you think Iniesta has a good understanding of when to play through balls? Therefore we should be able to agree someone who matches Iniesta's success in playing them is doing something right:
Plus, as we've already discussed, Van Gaal has said Herrera is one of the best passers at United and if anyone should know its him. I'm sure Van Gaal values possession as much as you say you do, if not more.
Ander Herrera is a top class midfielder. He is not sloppy in possession. He does not lack decision making or judgement when on the ball. Is he the finished article? No. However, the criticisms you're making of him are very wide of the mark. I'd be surprised if anyone who has watched Herrera on a regular basis would agree with any of the lines you're trotting out about him actually. The more you claim to know about Ander Herrera the more you come across not knowing much about him at all.
