That's a great point. I'm tired of hearing about managers and their "system" (looking at you, Martinez). An experienced manager should be able to come in, see what they have for a squad and what the player strengths are, and create a formation and lineup to best maximize whatever potential there is. After that it's up to the players to execute. Put them in a position to succeed and see what happens - that's all you can do really. Although with this group that would be a tall order. Half these guys seem to be happy just running around out there and collecting a check.
I'm not sure about the last point.
I have not seen any player shirking responsability or downing tools and I feel that they care, I just think they are by and large pretty crap at football.
Spot on with the other stuff, modern football seems to have dictated that the manager is the important part rather than the team, the manager should be looking to make his team work to the best system with the tools available rather than the players trying to adapt to the managers style.
I'm struggling to think of a manager who can even do that these days, they are all typecast and have their way of playing and thats it.
