You keep missing the point. At this point, you sre either
a) being purposefully obtuse or
b) genuinely don't see the point I am making, and are thus conflating it with the discussion of whether he should be here or not
I do like him, yes, but it is clear that his time here has passed, all good, the manager knows what he wants. As I have said in several places, the manager has made it clear via his system that Dier is not part of things. Onwards, but with respect. My point with you was your dismissive 'stick him in the u-21s'. The way you stated that came across as disrespectful. If you can't see that/don't agree, then this is a pointless exchange. I believe pros, especially senior pros, deserve dignified ends to their time with us. Dier is absolutely among that number IMO.
FWIW I think he is absolutely aware of the situation, but is looking to see out his contract and go on a free. His choice. Yes, it makes things a little tougher for us, but that's the way the contract cookie crumbles...
