It's nigh on impossible to say, I would have thought. Even in the case of those about whom so many are certain, I'd suggest it's much less clear cut, not least as it depends on numerous factors.
To take just the example of Yaya: of course he might very well move on. But that will, I'm sure, be contingent upon us being able to identify and get somebody who is better than he as a deep-lying playmaker in the centre of midfield. Or perhaps Guardiola will look at it and think that, actually, in a team that will be far, far more compact than we are at the moment, Yaya is still capable of playing that role at the highest level, without having the problem of a huge 20 yard gap behind him?
Personally, I don't think that there will be as big a turnover of players as some are suggesting (or hoping!). I reckon Guardiola will be happy, by and large, to work with what he's got, with one or two key additions. I don't really hold to the view that we have six or seven who are not 'Guardiola players', not least because of the sheer variety in the way that he sets his teams up. At the weekend, for instance, he played what would probably be written down as a 3-2-4-1 formation, with Kimmich, Badstuber and Alaba at the back, Lahm and Alonso in midfield, then a four of Coman, Costa, Müller and Robben in behind Lewandowski. He just seems to see the game differently to pretty much everyone on the planet, so it's difficult to second guess who he will/won't want.
