"We very much hope that Matt will choose to stay at Carrow Road for the final year of his deal," Chief Executive Neil Doncaster told the club's official website.
"However, we would obviously respect Matt's right to return to Sweden in accordance with his contract if he wished.
"In the event that Matt does decide to go, the full amount of any transfer fee and all savings in wages would go straight into Nigel Worthington's transfer kitty."
