Totally agree about the interest having to be there, and Gestede is one player where there probably isn't any interest. In terms of your first question, I was thinking more of players like Clayton (who I'd be sorry to see leave us, even though he's probably on higher wages than his recent contributions have justified). I'm sure lots of Championship teams would be interested in signing him, and the same with Saville, Johnson et al.
Second question - as I've said, lots of clubs have money to spend in this window. Again, I agree they probably wouldn't want an injury-prone striker who's scored two goals in as many years, but the likes of Saville would have more appeal to clubs around our level.
As for your third question - we've just signed a goalkeeper who only had six months left on his contract, but we didn't want to wait til the summer and sign him on a free. It happens, for a variety of reasons.
The window so far imo has been relatively successful.
Shifted a high earner of wage bill, got a good fee for him and got a replacement for a quarter of that fee.
Bought 2 players for the attacking 3rd of the pitch we needed who on early signs will make a significant contribution.
Get even 1 CB in and i think all things considered it will have been a good window.
Don't take this as a dig. But their has to be an actual level of interest in those players from other clubs, plus you then have to have the feasibility of any potential transfer factored in.
Use Gestede as an example; he is 31, allegedly he is on £30k per week, has a poor injury record and hasn't exactly pulled up any trees in the Championship with us (Ignoring his efforts with Blackburn 5 years ago). He also has a contract that runs out this summer and we are not looking to renew.
What clubs in our division would actually want to sign him? Then factor in the 2nd question of who could afford him?
Then as a 3rd question, if as a club you wanted him, but couldn't afford him, why not just wait until the summer and sign him on a free?
We tried to sell him last summer though. He might be in the side by default because of our defensive situation. I wouldn't personally select him in our best XI however. I don't think he's been a particularly good signing, his performances haven't been all that good and he's on decent money 🤓
