The 19-year-old was one of a host of players shipped out on loan this summer, with the Blues announcing Christensen would join Borussia Monchengladbach on a one-year loan deal, with the club having the option of making it a twop-year deal if things went well.
It's fair to say that at this stage, the former German giants won't be taking up the option.
Christensen has made only one league appearance for his new side, with Monchengladbach enduring a horror start to the campaign, losing all four of their games so far after finishing in an impressive third place last season. Christensen's only appearance came in a 4-0 loss to Dortmund on the opening day, with the defender being shunted to the bench since then.
Things haven't gotten any better for Die Fohlen, conceding 11 goals and sitting on the bottom of the Bundesliga ahead of their opening Champions League fixture at Sevilla on Tuesday. Despite this, manager Lucien Favre has elected not to go back to Christensen, despite the Danish international's availability.
With Chelsea also struggling in the Premier League, particularly in defence, Jose Mourinho decided he need to shore up his defensive reinforcements late in the window. Although recalling Christensen, probably the most highly rated of his centre-halves out on loan, would have seemed the logical option, Mourinho instead opted to bring in two virtually unknown defenders in the shape of Papy Djilobodji (Nantes) and Michael Hector (Reading) for a combined total of £6.7 million. This surely indicates the level of confidence the Portuguese manager has in Christensen at this point in time.
It must be said that Christensen still has plenty of time to turn his time at Monchengladbach around. The season is only a few games old, and with the club competing in the Champions League, as well as all three domestic competitions, Christensen is sure to see some game time.
The defender, who is still only 19, was the subject of intense bidding between the likes of Arsenal, Manchester City and Bayern Munich in 2012. There is no doubting his potential, but at this stage, he must surely have been expecting a brighter start to his Germany for both himself, and his loan team.
