I think he's more likely to go than Adam, unless Lallana hustles hard for a move. We'll be able to get some kind of value on Shaw that if reinvested won't massively weaken the team. For what we'd get for Adam vs what we'd lose it's probably not worth our while selling.
But easier to talk Shaw out of a move...he is scarcely out of leading reins. Adam would have a valid reason to ask for a move at his age.
