The Norwegian has entered the final year of his contract and has already made it clear he wishes to move on from the Scottish Premiership side this summer.
The 23-year-old has long been linked with a move to Milan but no concrete offer has been forthcoming from the Serie A side. The Scottish Sun now reports English Premier League newboys Norwich are ready to take advantage with an eight-figure offer for the international centre-back.
Meanwhile, Celtic are said to have made a £3.5 million bid to Bologna to re-sign former youngster Aaron Hickey
The left-back left his boyhood heroes to join Hearts before making the move to the Italian side in a £1.5 million deal last summer. He’s impressed during his 12 appearances but Bologna are said to be ready to cash-in with a quick £2 million profit on the investment.
