Undav has been outstanding on-loan with Stuttgart this season.
"Definitely," the attacker replied on Friday evening after the 1-0 victory at FC Augsburg to a question from a DAZN reporter.
"I've said what I want often enough. Now we have to wait and see what happens. The ball is in Stuttgart's and Brighton's court."
VfB can sign the Germany international permanently with a purchase option of between 12-18m.
