When was the last time I mentioned it?
It's a reality Pedro put his preferred system in the bin. So if he knew what he was doing then I'd suggest that's strong evidence he actually didn't know what he was doing. And remember he had several months in Scotland playing at the sharp end to arrive at that plan.
It strikes me as very obvious that Pedro had a style his whole career based on counter attacking and that he has never managed a team that effectively required to win every game. That gap has been obvious from the first serious test he faced. It's been a factor of his team's style at Rangers that we are often prepared to give possession up.
Do I see improvement? Yes I do but I don't think we needed a manager who was learning as he went.
I would say that is good management ditching your preferred system. Some managers only have 2 plans, plan a and do plan a better....
