Agreed that it was a good job for him. But I think it will continue to be a good job for him next season (assuming they stay up). Expectations have probably never been lower at Villa Park. A lower mid table, avoiding a relegation scrap, season will be seen as progress of a kind. They've also shown themselves fairly patient with their managers compared to some other PL teams.
If he can get a couple of good signings come the summer, perhaps he can even get a Spurs player on loan to do well, I think he will do fine again next season. I remain entirely unconvinced by him as a long term manager, in part because he's entirely unproven at that. But he's also shown himself as capable short term at least, and that should be enough to keep the Villa job for a while.
