I don’t think any manager would come under the implied constraints you are alluding to. When he himself says he was brought in to play a certain way and has gone against that I’m pretty sure he is referring to SR bringing him in to play a certain way (the way he played to get Luton to where they were). He is now throwing the people that changed his mind ( the players as already stated). IMHO it doesn’t matter who he took council from, the buck stops with him as he is the manager that has final say and it’s him that implements his decisions (irrespective of how he came to those decisions). He is either very weak or a puppet neither of which are great traits for a football manager.
