Q8, what it actually means is that he expects every player to give 100% in every game. You can read several things into this—anyone who doesn't give 100% is out, for starters—but I don't see big changes there.
Well, it depends on whether they wake up from their post-carling cup slumber as they have clearly not been giving 100% since then. If they sleep till season end then you can very well expect big changes. No point in keeping a team that remains happily ever after when they have only won 1 cup.
I see midfield as a key area of change in the summer and shifting out of some deadweights.
