Cheeky when newly arrived (5)
I believe the answer is:
fresh
This clue is a double definition.
'cheeky' is the first definition.
(I've seen this before)
'newly arrived' is the second definition.
(I've seen this in another clue)
'when' is the link.
(Other definitions for fresh that I've seen before include "forward" , "Cheeky (sl.)" , "Saucy" , "Recently picked" , "Newly picked" .)
