The Italian giants are reportedly resigned to losing Mehdi Benatia during the next week, with Arsenal said to be interested in the Moroccan.
Tuttomercato are reporting that Christensen is their first choice to replace their outgoing defender - but Chelsea have already rejected the loan offer.
Christensen was a regular in Antonio Conte’s Chelsea side last season, playing 40 times in all competitions including a start against Barcelona at the Nou Camp.
The defender made a mistake in that game that allowed Lionel Messi to score, but Conte backed the player to bounce back.

David Luiz and Antonio Rudiger have played really very well, so it's not easy to change
Maurizio Sarri
The rift between Christensen and Sarri took a turn for the worse last week after the defender allegedly used the toilet 15 minutes before half time during the defeat against Arsenal.
Christensen’s father told Danish TV in December that his son would seek a move away from the club if he didn’t start playing, to which Sarri promptly responded.
"The father? I'm not interested... the father? No," Sarri said.

"What can I say? I think that, in the first part of the season, David Luiz and Antonio Rudiger have played really very well, so it's not easy to change.
"I think, also, that in our last six matches, Christensen has played in three of them.
“So I think for his father, maybe the Europa League is not important. But for us, it's important."
