I think he's a good manager, certainly a damn sight better than what we currently have. Is he good enough to compete with Klopp and Pep? I don't know, possibly not. But there's no sentimental attachment towards him. In fact due to him managing our rivals its more likely fans will turn. I see that as a good thing. If he's a success then great, but if not we can get rid without too much drama, and by then perhaps someone even better will be available.
We just need the board to stop handing out contracts as if they were sweets, and we need to get into the mindset that managers are disposable; we're not going to find another Ferguson. I see no harm in hiring a good manager, giving them a year, assessing their performance during this time, and if its not cutting it, be working in the background to bring in a replacement at the end of the season. More proactive, less reactive.
