When Norwich tried to buy Iversen in August, they were told to come back in January. This they did.
"There came a bid Rosenborg did reject, but we are expecting a new bid this weekend," Iversen's adviser Christian Eidem told Norwergian daily Dagbladet.
The bid is said to be just 200,000 punds. RBK are in principle not willing to sell.
"We know we have many good players, but this mostly is about the timing. We are beginning a really important season for RBK. We want to return to the top of the league, moreover we have a good chance to enter the Europa League. This is the most important for us," director of sports Erik Hoftun said.
