Nice have stated that they have no interest allowing coach Lucien Favre to join Borussia Dortmund amid reports linking the former Borussia Monchengladbach boss with becoming Thomas Tuchel's successor.
Tuchel left his role as Dortmund coach on Tuesday, with Favre widely linked as a prime target for the Bundesliga club after leading Nice to third place in Ligue 1 this season.
But Nice have responded strongly, insisting that they have to prioritise sporting success over financial gain, while claiming "the chapter is already closed".
A statement released by the club on Friday read: "While the media circus around the interest from Borussia Dortmund for Lucien Favre intensified this week after the departure of Thomas Tuchel, OGC Nice wants to announce its position - publicly and once and for all.
"It is logical that a coach of his calibre, at the end of such a season [as he had] in Nice, arouses covetous glances of the biggest European clubs such as Borussia Dortmund, quarter-finalist of the last Champions League.
"It is equally legitimate that this opportunity may arouse the interest of Lucien Favre. OGC Nice has no difficulty in understanding this.
"However, in view of the proximity of the resumption of training (June 19), the club does not wish to follow up any negotiations concerning a transfer of its coach, under contract until June 2019.
"The sporting interest prevails on the financial side, as the Nice management has always asserted.
"This decision is firm and unequivocal. It was fully heard by the leaders of BVB and, of course, also by Lucien Favre, who perfectly understood and accepted it.
"Once opened, the chapter is already closed. So, with a pleasure identical to the one he has always testified, he will continue his mission at the head of the Nice team in 2017/18."
