Direct extra to spot (7)
I believe the answer is:
oversee
'direct' is the definition.
(I've seen this in another clue)
'extra to spot' is the wordplay.
'extra' becomes 'over' (both can mean left over).
'to spot' becomes 'see' (I've seen this in another clue).
'over'+'see'='OVERSEE'
(Other definitions for oversee that I've seen before include "Keep an eye on like foreman" , "Be responsible for" , "Disregard" , "survey" , "Supervise, keep an eye on" .)
