Evaluating the players is difficult, because they're only worth what people are willing to spend on them.
I do like how Ian Burchnall insists that they're our players, but the club will have in mind what price would be tempting and, I would imagine we'd try to negotiate the best deal possible. This said, my value won't likely be what the club might seek, but it is what I would ask.
Replacing them is difficult. There is a chance we might be able to swap players, but obviously, this could come at the risk of devaluing any player.
Until a player sold, I won't personally worry about replacing anyone - yet the club clearly has their own eyes on players.
Ruben Rodrigues - £500k to £1million
Kyle Wootton - £750k plus sell on clauses
Cal Roberts - £500k due to his injury issues
Richard Brindley - £250k to £300k
Dion Kelly-Evans - £20k to £75k
It will be interesting to see what others price the players at themselves.
