Difficult task (4,5)

Ross

I believe the answer is:

tall order

'difficult task' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for tall order that I've seen before include "Difficult demand" , "Formidable task" , "unreasonable request" , "Unreasonable demand" , "Challenge" .)

I've seen this clue in The Telegraph and The Independent.
