I agree with this. However, I do think that if we were to be promoted at the end of the season the club would find the money. Points 2 and 3 are more likely to stand in the way, and also he will be firmly on the radar of the larger clubs, so as you say we have zero chance of getting him.
I just hope that the club are planning ahead of a life without Harvey Barnes, and identifying long term suitable replacements. However this is the Albion we are talking about......
Incidentally, I saw on the BBC yesterday that Brighton are lining up a certain Dan Ashworth to be their new D of F.......I am sure he could source Harveys successor.
I'm still not sure that being Leicester born & bred would stand in his way, especially if he couldn't get regular playing time there.
I'm sure I saw another post when Leicester recalled him from Barnsley last season, he only had a few minutes on the pitch. I think a regular first team slot for us in the Premier League could be attractive to him, especially if he had International aspirations.
I'm also sure I've seen the Dan Ashworth story before. Just can't see him going to Brighton. IMO he has unfinished business in the England set-up, & if he did go back into club football, it would be at a more fashionable club than Brighton.
