It is worth remembering that Brighton have their own top prospect, Ben White, looking to get game time and have admitted they have a great depth of CBs.
Thus for me these fees for Dunk are a joke and personally I would not entertain them. If Spurs wish to pay 45mill, let them.
We found great value in deals with A**x and RB there is no reason to go nuts now.
I get the sort of money being talked about for Havertz based on his age and the talent he supposedly has. If Hazard was once more leaving Lille would we not all be happy at structuring a deal around 90mill to have such a player? Heck we got basically 120mill for him after paying 32mill. Havertz could go for 180mill in 7 years.
Brighton have a need to sell. Most teams do, they also have cover in that department so no need to buy a replacement.
Given his age and no resale value in this market we should offer between 20-25mill for Dunk. If Brighton do not accept, so be it.
