Reports have suggested that Southampton have made a £5million bid for the 20-year-old defender.
Reports also claim that Arsenal and Inter Milan are interested in the Denmark international defender.
Boilesen told ekstrabladet.dk: “I have not heard anything about it yet. Someone from the Dutch press told me about it 10 minutes ago that is all I know right now.
“Therefore it is difficult for me to have an opinion on these rumours. For now I am concentrating on my rehab here at Ajax.
“But, I am very flattered if it is true that a Premier League club has made an offer for me.”
