Pearce, though, has warned those contemplating a formal approach that he and a supportive board at the City Ground have no intention of sanctioning sales.
He said in the Nottingham Evening Post: “Henri is not somebody we would be keen to sell.
“I built a good rapport with Henri through the international years, he is a very good player in this league. We want to hang on to our better players, it is as simple as that.
“The fact that there might be interest in him or in one or two of our better players is not a concern.
“We want to create a culture where hopefully there will be scouts coming to look at six, seven or eight of our better players in the future.
“I have an owner who wants to grow the club, rather than dismantle it.
“I think we are in a good position. You worry when there is not any interest in your players, because that tells you something about your squad straightaway.
“We will discuss every offer that comes in. If we think we can take the club forward by selling and reinvesting, then brilliant.
“If I, as a manager, know that we sell players and it will not be invested back into the club, then there is no real drive for me to sell a player.”
