The Danish centre back has been excellent for Chelsea under Thomas Tuchel and his contract expires at the end of next season.
It will be interesting to see if Chelsea can convince the 24-year-old to continue at Stamford Bridge beyond his contract term.
Christensen has been at Chelsea since 2012 and he was highly rated at the London club.
However he fell down the pecking order since the arrival of Frank Lampard and he was expected to leave permanently.
The defender seems to have resurrected his Chelsea career since the arrival of Tuchel and it remains to be seen if he can continue to hold down a regular starting berth for them.
Silva qualities outlined
Meanwhile former PSG defender Thiago Silva has made quite an impression since his move to Stamford Bridge and his former teammate Marquinhos has now outlined the Brazilian’s impact on him and other players.
He said: “I love playing with great players. Thiago Silva, it was exceptional to play alongside him. I learned a lot of things just by watching him play in training. It was important for my experience.
“We spent good years together. I made good progress alongside him. Presko [Kimpembe[ the same. He also took advantage when Thiago was there. We three exchanged a lot to improve, to push each other.”
It will be interesting to see if Thiago Silva can have a similar impact on young Chelsea players like Ben Chilwell, Reece James, Andreas Christensen and Kurt Zouma.
