The Yorkshire giants come into the match against free-spending Middlesbrough with seven losses in their last eight league and cup matches, a record that Christiansen will be desperate to put behind him with his job on the line.
A number of first-team stars have been the target of criticism from sections of the Elland Road crowd in recent matches, with a handful of summer signings yet to prove their worth.
Felix Wiedwald has been dropped to the bench after conceding 12 in his last five matches, while Ezgjan Alioski has managed just one goal all season. Matuesz Klich, Pawel Cibicki and Jay-Roy Grot have all hardly featured.
But Pierre-Michel Lasogga is perhaps the one summer signing that has failed the most. Managing just five goals all season, with two coming in a 5-0 thrashing of Burton, Lasogga was expected to be the star striker to fire Leeds towards the Premier League.
Fans hopes of a striker that would blow away Championship defences grew even further when the Yorkshire Evening Post reported Lasogga was earning a huge £50,000 a week at parent club Hamburg, of which the Germans are paying 75 per cent during his season-long loan.
But those dreams have evaporated. Hauled off the pitch at half-time by Christiansen against Brentford, it is about time the Leeds boss hands Caleb Ekuban the chance to shine after he recovered from an operation on his foot.
The Ghanaian striker, who signed for Leeds from Serie A outfit Chievo in the summer, has been limited to just two senior appearances.
Scoring and creating another goal on his debut during Leeds' 4-1 win over Port Vale, the 23-year-old impressed from the off against Sunderland before suffering the injury.
Born in Italy, Ekuban boasts blistering pace and a delicate first touch, as well as instinctive nature in the final third. But he can be just as physical, and showed that in the Albanian Super League last term with 17 goals for FK Partizani on loan.
Unknown to Championship defences, Ekuban could be the secret weapon Leeds are crying out for.
