Again - an excellent post. And the analysis of Arteta's big weak spot in this thread is spot on. It's so disppointing that we 'armchair' analysts can see that the manager's bullish perseverence with a system that the players have lost some confidence in; is not suited to every single game and has been worked out by other teams over the course of the season - not to mention unsuited for second choice players - but the manager refuses to accept this and change things up. It's also self-defeating that he insists on playing his 'favourites' while potentially able back ups who might at least add a little variety are discounted as starters.
What I would say is that last nigtht was not a time to suddenly change things. West Ham away and Southampton at home should have been used to tweak the system to see whether more protection could have been given for Holding - alternatively leave him out (eg Zinchenko at RB; White at CB and Tierney at LB, and Jorginho alongside Partey) but this opportunity went begging.
We saw this 2 seasons ago - when we started to look so rigid and ineffective and ball progression to our forwards dried up. And we are seeing it again now - albeit with a system that has served us well until it really counted. The players last night need to have a look at themselves, but our collective loss of confidence is not just down to 3 disappointing draws - its the players realising that our set up is flawed and lookign a bit tired. Arteta's refusal to change things up looks passive and fearful, and if our players look scared - which they did last night - this has to a degree been transmitted by Arteta.
One final point. If ever we wanted evidence last night as to why Citeh sold us Jesus and Zinchenko - it was there last night in neon lights. Its lamentable that these so-called 'winners' that were bought to take our team to the next level went hiding last night. The real question is not their talent (albeit that Jesus is showing that he is not a reliable goal scorer), but their mentality. And that is a worry for sure.
