Again, see the bigger picture.
Ancelotti building the club up, getting a stable base is a long term project. Does not necessarily mean he will be here to see it out.
Yes, he has been at clubs for no longer than 2 years, since Milan but then the argument could be said they were all short term success sacking clubs. You look at those clubs and see a general consensus that all managers only last a short period of time (Zidane being the main exception).
He has constantly talked about how he loves it here and not just the club. He loves the area and everything that comes with it.
Hi son is here, I jokingly talked of an Ancelotti dynasty but it would not be shocking to see Davide being propelled more and more into the forefront.
I am not factually saying it will work out but you seem 100% that Ancelotti is not a very good fit at this club, despite the positive signs, I see that he very much is a positive to the club and we have started on that road to being relatively successful and maybe more.
