It all depends on how you define 'part of the success'...what I know (which despite invitation I am not prepared to share) suggests that one's definition of such a thing would be vital in determining one's answer.
I think it's ironic that now there is a view that 'everyone' at the club was part of that win, whe the truth is, no-on actually thought he would do it - and that includes most fans.
In the holistic sense, of course a great many people can claim a piece of that win in terms of work done to get the club to the footing it is on (a good friend of mine who worked there for many years celebrated in Bilbao with the team/staff precisely on that premise). But the literal work? It was a small group of people who threw their lots in with each other. I will say that if you think of the people who decided not to sack him in January as being part of the group who led to this success (by proxy) then yesm, the group grows wider than Ange, coaches, playing staff/meds, and squad.
