Halmstads BK chief Fredrik Andersson says they're delighted with the progress of Sead Haksabanovic.
The 17 year-old Swede is being watched by Manchester United and had a training stint at Carrington last season.
"Foreign clubs are showing interest and it is quite widespread, from many different countries. The interest is huge.
"Clubs and agents call every day and ask questions about Sead," Andersson told Fotbolltransfers.com.
"Sead has characteristics that allow him to develop in our environment and become even better. He is one of those prospects who is most interesting in Swedish football."
