Good point. But it needs to said, that the task became more and more difficult as the squad deteriorated more and more into an assembly of big names and big promise but without hard work and right mentality. Also I think, Ole doesn't really suit your point in being unwilling to adapt - with him it was rather his inability to adapt (or recognize the issues).
The squad has never been an assembly of big names, that one is a total fallacy. And it definitely applies to Ole who had his favorites who could play absolute trash and still start week in week out, he also refused to rotate the team in spite of the fact that he experienced a catastrophic series of muscular injuries during his interim after playing the same 11 into the ground.
