Stefan Kiessling is currently attracting attention from major clubs in Germany, England and Spain according to his agent Ali Bulut.
The striker has shot to the top of the Bundesliga scoring charts with 12 goals in 14 league games this term but Bulut is confident that a deal will not take place until the summer.
The news will be please Bayer Leverkusen who will not want to lose the 25-year-old mid-season with the club currently three points clear at the top-of-the-table.
Kiessling has enjoyed a relatively modest career to date but his form this term has seen his asking price rise to a reported €15million although Bulut is quick to point out that his client is more than happy at Leverkusen.
"Biggest clubs in Germany, England and Spain have asked the boy while I haven't had contact with Juventus, Inter and Milan or other Italian teams," he told Calciomercato.it.
"However at the moment there is nothing concrete with any of these teams. The boy is fine at Bayer Leverkusen and he won't move in January.
"In the summer we will see but it is also possible that he remains another season, the team is going very well and he could play in the Champions League next year.
"The price? Surely it is more than €15million."
