If Dunk says he wants to go and he has outgrown us then of course by all means let him go and take the most money. What I am exasperated by is people who revel in touting our best players and assuming we can't keep them.
Really don't understand this selling the best players line. If we want to progress we need to keep our best and attract better players in those positions where we are weakest. Yes we could make a lot of money but equally we could spent it on a replacement who is crap
