The Dutch midfielder has had two separate loan spells with PSV over the last two seasons and Brands says they're now seeking a permanent deal.
He revealed: "Marco has had a positive conversation with (coach) Phillip Cocu. I'll now go to Chelsea for talks to see what the possibilities are.
"It would be good to buy him as far as we are concerned."
A move for Tottenham striker Vincent Janssen is also on the agenda for Brands.
AD says they'll move for the former AZ star if Luuk de Jong leaves this summer.
