The 21-year-old has expressed his desire to move on from Feyenoord this summer but, according to his coach, there have been no clubs enquiring for the defender
The versatile defender, 21, has set his sights on a summer move, with AC Milan being heavily linked to the Dutchman.
However, Koeman claims that there have not been any offers on the table for Netherlands international and is hopeful that the situation can be resolved early in the summer transfer window.
"To date no club has enquired for Bruno," he told Voetbal International. "We will just wait until he’s back and then we’ll see.
"It seems clear that Feyenoord want to know where they stand. If we complete a deal [with Martins Indi] next week, we will begin work on the team. It is nice to know about which players you have available."
Martins Indi is under contract with the Eredivisie club until June 2016.
