The Whites went down 3-0 to Wednesday away from home at the Hillsborough Stadium in the Championship just before the two-week international break.
The loss to the Owls followed a 3-1 defeat to Cardiff City away from home at the Cardiff City Stadium in the league.
Christiansen has admitted that the defeat to Wednesday was his worst so far as the head coach of Leeds.
"It was the toughest defeat I've faced so far,” Christiansen told The Yorkshire Evening Post regarding the defeat to Wednesday.
The performance of Leeds against Wednesday left much to be desired, and the fans will expect the team to bounce back.
The West Yorkshire outfit will return to action on Saturday afternoon when they take on Reading at Elland Road in the Championship.
The Royals’ start to the 2017-18 campaign has not been great, and it is hard to imagine Leeds dropping all three points at home on Saturday afternoon.
