Bundesliga outfit Schalke are planning to make a bid for Rosenborg star Per Ciljan Skjelbred.
The 23-year-old, who has been linked with an exit from his current employers for some time, has hinted recently that he could be tempted to move on.
The Norwegian midfielder has got only 18 months remaining on his current contract and Rosenborg will be keen to cash in while they still can.
They are, however, keen to hang on to Skjelbred until they have negotiated their upcoming UEFA Champions League play-off against FC Copenhagen.
"We know about the interest from Schalke and there has been some contact," Rosenborg director Erik Hoftun told Adresseavisen.
"We have talked to Per about this. But an offer has to be good if it is to be accepted."
Skjelbred's agent, Andreas Ekker, has also confirmed that the interest from Germany is serious.
