Off contract this month, the Dane is expected to join Barcelona.
"I know what to do," the 26-year-old told Bold.dk.
"It's not just up to me when it will be published."
Christensen did not want to confirm that it will be Barcelona, but took the opportunity to praise the club.
"It is one of the biggest clubs in Europe, and even though they have had some problems, it is still one of the biggest clubs for a player to go to."
