The versatile defender has caught the attention of the Serie A giants with his fine performances, but the San Siro side are yet to make a formal approach
The Serie A giants have long been linked with a move for the Netherlands international and a number of recent reports claimed that the Rossoneri have made a formal approach for the defender.
However, Van Geel has insisted that Feyenoord have not yet received an offer for the 21-year-old.
"Everything is quiet for now around Bruno. We have not heard anything [from Milan] at this point," the director told Algemeen Dagblad.
Martins Indi is a product of the renowned Feyenoord youth academy and has developed into a key player at the Rotterdam giants in the past two seasons.
The centre-back has a contract with his current club until the summer of 2016, but he could be available for a fee in the region of €8-10 million (£6.83-£8.5m).
