Spot on mate. Good young players will always benefit from playing with better players around them. It's part of their development process. I'd think the players you mention will be excited to think they'll be playing with other lads they can really learn from.I don't think people are going that far tbh, just hoping the club get the balance right which I think they will.
I'd imagine players like Rigg, Mundle and Mayenda will be excited at the thought of Enzo, Diarra, etc coming in and seeing it as a benefit.
But there'll be a few 'casualties' and, as sad as it is, I expect some will believe they're better off elsewhere.
I have a few in mind but I won't mention them until I'm sure.
