Lallana's been injured for an age, how can he possibly feel like he's been pushed out

Where have you seen this suggestion? I agree it's not looking good for him but that's from a outsiders perspective, Adam should believe he is good enough and be willing to fight. If not, **** him, that attitude deserves to be sold!
Clyne may not be rated but he's the only recognised traditional RB we have.
TAA is a CM, Gomez is a CB, Fabinho is reportedly a DM, Milner is a Jack of all trades. He's not going anywhere imo, certainly not without someone else arriving.
I don't think either are good enough any more but don't think either will leave because we want a squad.
Lallana or one of many CMs but I think he'll stay because he can play in the front three too.
