But a source in Paris familiar with the situation who declined to be identified because of the sensitive nature of the negotiations said the sticking point is that Mr. Jacobs and Mr. Duffy want to bring the entire Vuitton team to Dior, potentially creating a delicate situation both at the house of Dior and at a denuded Vuitton.

In the announcement of the business changes, Mr. Arnault praised Mr. Carcelle for the growth of Vuitton since he took control in 1990.
