Brondby sports director Per Rud says they're prepared to sell Simon Makienok for the right price next month.
Crystal Palace chief Iain Moody has the young centre-forward under consideration for the winter market.
Rud remarked to BT: "At the moment there is nothing concrete with Simon, but we'll deal with it, because we have promised both him and ourselves.
"We owe it to our shareholders to consider any offer, but basically we are really happy with him and see him staying here.
"We do not need to sell."
