According to reports in Italy, the Dutch defender is seen as a possibile replacement for Alex Sandro, who is set to join Paris Saint-Germain.
The 27-year-old played a key role in Palace's survival last season, scoring five goals in the Premier League.
"I am feeling good and I want to keep doing that, but I am a Palace player and I am looking forward to the season.
"I am happy. We have got a great squad, my family lives in London, my kids go to school here.
"It is just a rumour and unless there is really people coming in then I will never worry about it."
