I disagree on Crouch, I rate the player and he'd be a success in Spain. The problem being that perhaps he's not good enough to be first option in Real Madrid and Barcelona, and currently, Portsmouth or Aston Villa can pay more wages than Atletico or Valencia.
But Crouch would be a success like Nicola Zigic has been, another very tall player.
About Rafa's plan, the plan wasn't to get the hang of english football, the plan was to make us challenging for the title again. And yes, he's on his course.
With the one year plan lines, surely you don't mean that Mourinho with the same resources that had Rafa when he came here would have done the job, right?
If Rafa receives a new contract now, I'd ask him to challenge next year too. But 5 years ago, I wouldn't have asked a 2 years plan not to Mou, not to anyone. There was a long way to go.
