The Rotterdam outfit have been without a coach since Erwin Koeman quit at the beginning of last month following their seventh-placed finish in the Eredivisie.
Jacobs told AD Sportwereld: "We are doing our utmost to make sure that Bert van Marwijk can´t say no to us anymore. It matters a lot to us to present this coach very soon. This isn´t only because we have a lot to do for the new season. That is in fact already on track."
