Speculation has been mounting for some time that the 18-year-old defender could be allowed out on a season-long deal in 2014/15.
Sunderland are reported to be leading the chase for his services, with Gus Poyet prepared to offer the youngster a Premier League stage on which to perform.
Christensen has, however, not given up on taking that step at Stamford Bridge – with Chelsea holding the promising centre-half in high regard.
His representative, Sten Christensen, told Danish publication BT on the loan rumours: “That is news to me.
“I do not believe that Andreas will be joining Sunderland for the upcoming season.
“That is not my impression right now. I have not talked to the club about a loan for Andreas.
“At the moment, the plan is that Andreas will play for Chelsea when pre-season starts after the summer vacation.
“But things can change quickly in this game.”
Christensen is under contract at Chelsea until the summer of 2016.
