I mean I'm sure even they're aware of that tbf.1. Yes
2. Fine to challenge, if at any point I'd suggested he'd be a starting CB. At 36, I'm not sure he'd be expecting it either
3. It's not a bizarre response to think that one of our other 2-3 centre-backs would start ahead of him, while he would be a good option off the bench. Thinking he'd be a good addition to the squad does not mean I don't think we don't need another CB, but I definitely think he'd help improve what we've got with advice and playing time in training
He's £3m and playing for Union I doubt he'd be on huge wages. Hey, Union are going through a great period in their history and maybe he just wants to be part of that. Who knows?
Funnily enough, they're talking about the move on Talksport now (H&J at around 14:02) and saying what great experience he'd bring to the club and how he might not be a starter because their starting backline is pretty good.
Maybe you can phone into Talksport and call their correspondent a moron?
Where we differ is that I'm of the opinion that EVERY player signed (starter or sub) should be able to fit into the system we play and we shouldn't make exceptions. That's why players like Dier are now redundant.
