The 24-year-old struggled for regular action with the Blues during Maurizio Sarri's time as head coach and was consistently linked with a move away from the club.
The Denmark international has been a regular under Frank Lampard, though, making 23 appearances in all competitions and starting 10 of the club's last 11 Premier League matches.
Christensen declared his "love" for the London club before suggesting that he would be open to extending his current deal, which is due to expire in the summer of 2022.
"I've never looked anywhere else," Christensen told Sky Sports News. "I've never doubted my situation. I've always had my eyes at Chelsea.
"I've had my contract and I've always expected to finish that and I've always dreamed of even more than that. Nothing has changed. Obviously it was a different situation last season but I still love being here, that's the short answer."
Christensen played the full 90 minutes as Chelsea suffered a 3-2 defeat at West Ham United in the Premier League on Wednesday night. body check tags ::
