The 26-year-old is in South Africa with the Dutch squad ahead of the World Cup, and had been reported to be top of Harry Redknapp's transfer list.
Spurs boss Redknapp is keen to bolster his attacking options, having secured a place in the Champions League qualifiers for next season after finishing fourth, and is reportedly ready to offload Robbie Keane to Aston Villa.
However, former Ajax striker Huntelaar insists he has unfinished business at the San Siro, having arrived from Real Madrid in a £15million move during August 2009.
"I see my name in the Italian newspapers and I don't understand why," Huntelaar said. "I would like to know who has said that I will be sold, because it doesn't seem like anyone from the club has said anything.
"No other club interests me: my agent has never spoken about a transfer and I want to stay at Milan.
"I will not leave Milan until I have demonstrated my worth."
