Like what? I'll be dammed if I notice any change. There used to be but nothing I noticed since 2012.
All sorts of things change:
- whole team stuff such as to whether there is any effort to press or if they just retreat and sit deep
- the general tempo and directness of the play
- the organisation of the defence - whether it is zonal or marking - largely depending on the opposition
- how high up the wing-backs play and whether they are just holding wide or trying to make penetrating runs and whether Juve are putting on emphasis on attacking down one flank in particular.
- how Vidal's and Pogba's roles are interpreted during a game changes significantly from week to week
- Are the forwards playing as a pair or one behind the other and how are they moving in relation to each other and the rest of the team
And that's just pretty obvious stuff off the top of my head. Could give more examples and more detail if I had the inclination.
