Rosenborg young gun Markus Henriksen is attracting plenty of attention from around Europe.
The 19-year old Norwegian midfielder has recently emerged as a strong target for Scottish champions Celtic but they face a fight from German outfit who are also showing considerable interest.
"Hamburg have a good scouting system and know Markus very well," said Henriksen's agent Andreas Ekker.
Hoops boss Neil Lennon is prepared to part with £2.5million for the Norway international but can expect a fight now that Hamburg are on the scene.
