Christensen explained that quotes attributed to him recently from when he was in Denmark, describing words between him and Chelsea on his future, were not accurate due to translation.
He did reiterate that he said he would like to stay.
"I still have a long contract," he said.
"The club has done a lot for me, as soon as I signed a new contract I did not really have anything to think about."
"It is always healthy competition in the team," he said of the contest for central defence positions with the likes of David Luiz and Toni Rudiger. "We try to push each other and obviously it is not fun to be the one playing less. In the Europa League and the cup games I have been trying to show myself, and in training."
