I reckon we'll get about 100k for him. Decent player, but there isn't a huge amount of money in leagues lower than the premiership at the moment to start paying much more than that.
If it's true that all the Championship clubs are getting a £400k windfall as part of Birmingham City's parachute payment shareout then thats what we should be looking to get for Lynch, In effect they get a free player and we get a nice sum of money for a good young player.
