There's a lot of catastrophizing going on. Bar a stupid bid for Hackney from a top 6 Premier league team, he's going nowhere. RVDB will be on various radars but we have no need to sell. McGree is going into his last year so unless he signs a new contract, which doesn't seem likely, we will want to sell.
Last year, losing the loanees and Akpom ripped the spine out of the team. This year, even if we don't resign any loanees and lose McGree, you figure it's pretty easy to improve on them. Losing McNair and Dijksteel is hardly a big deal.
I think our main problem at this point is that too many of our new signings have spent the year injured including Coburn. At this point in time you can look at all of the following and be unsure if they will be good enough for next season.
Engel, Greenwood - played a fair amount but probably not good enough.
Banguara, Latte Lath, Coburn, Ayling, Thomas, Azaz, O'Brien, Silvera - Haven't played enough to tell.
Rogers - was developing well until he got sold.
For what it's worth, I think Thomas, O'Brien and Azaz will prove to be good 1st team players. Latte Lath is probably best off the bench. I doubt we'll keep Ayling. Coburn could do with a loan after he gets his injury sorted properly. I don't see Silvera ever being more than a middling Championship player but that's fine, we need a few like him as back-ups. Nothing wrong with Glover as a back-up but I could see us selling him if an offer comes in.
It could go horribly wrong. Thomas and O'Brien may have a storming dozen games each leading to us being priced out of an auction for them. Spurs may decide that Hackney is their #1 target. Our long-term injuries may span into the start of next season. Even if that does happen, leading to yet another major rebuild, we will have parachute payment levels of money to fund it with. Unlike last season where we needed to replace 6 first-teamers with around £10m, we will have the money we need to upgrade the missing players.
