AIK chief Bjorn Wesstrom admits they could sell star youngster Alexander Isak.
Liverpool, Barcelona, Real Madrid, Manchester United and Bayern Munich have all watched Isak this year.
Asked if a deal for eight-goal Isak could be one of the biggest in the club's history, Wesstrom told Sydsvenskan: "Absolutely."
However, he suggested the teams linked with his 17-year-old star man are yet to make their move.
"Then there is the question of what level you would be looking at," he added.
"But all that you get to decide when it becomes something tangible."
