Wassall was promoted from being the Rams’ academy director to head coach of the first-team following Paul Clement’s shock dismissal last week.
The 47-year-old has never managed in the Football League before, but he is set to remain in charge at the iPro Stadium until the end of the season.
And Wassall seems to have made a good impression on Derby’s senior players, with Christie suggesting that they are starting to come to terms with what he wants from them now.
“We’re adapting to what Darren wants from us after taking over last week and it has been good working with him so far," the full-back said. “As well as adapting we also have to pick up the wins as soon as possible.”
Wassall took charge of his first match as Derby boss last weekend, but he was unable to lift them out of their slump.
The Rams were beaten 1-0 by Milton Keynes Dons in front of their own fans, as their winless streak was extended to nine matches.
Derby have fallen all the way down to sixth place in the Championship table as a result of their recent struggles for victories, and their next match comes against Brentford at the weekend.
