I hope that he's made the improvements that were asked of him, if he hasn't then he'll think he no longer has to.
I'm not too bothered about his past, his future performance is more important. I’m guessing that this is his last chance and with a bit of luck he’ll know that and will stick in. On the other hand, he acts like a kid and is just as likely to revert to type.
I think for him to turn everything around would mean a total life change and him ditching his hangers on.
