Sevilla have been frightened off Danijel Pranjic by Heerenveen's asking price.
Heerenveen quoted £9 million for Pranjic when Sevilla came knocking last week.
The attacker is aware of Sevilla's interest and said: "It's nice to know.
"I'm also happy the club regard me so highly. I know that if I keep playing well, there will be a big club out there willing to pay what is needed for me."
