The in-form midfielder produced a magnificent display to inspire the Danes to a 4-0 victory over Group E leaders Poland in September.
They followed up with victory in Armenia in match eight of 10 to stay third in the group with Montenegro in second – although both teams are locked on 16 points and an identical goal difference. Poland recovered to beat Kazakhstan and stay top by three points.
Now it really is crunch time with two fascinating rounds of matches to conclude the group.
Denmark travel to Montenegro tonight (Thursday 5 October) in what could be a make or break match in terms of second place – only the nine group winners qualify for next summer’s finals in Russia with the eight best runners-up meeting in the play-offs.
However, Montenegro then have to travel to Poland in the final round of matches with Christian and Denmark at home to Romania.
“I guess it’s all or nothing, again,” said Christian, capped 71 times by his country.
“We need to win. We need to follow up what we did against Poland and Armenia. Montenegro beat us at home so we need to put that right.
“Montenegro have been very strong at home so it will be a difficult game but we have our hopes high.
“Hopefully we can get good results and try to get to the World Cup.”
