Team leader spots wreck (5)
I believe the answer is:
trash
'wreck' is the definition.
(I've seen this in another clue)
'team leader spots' is the wordplay.
'leader' says to take the initial letters.
'spots' becomes 'rash' (I've seen this before).
The first letter of 'team' is 't'.
't'+'rash'='TRASH'
(Other definitions for trash that I've seen before include "bunk" , "Rubbish, worthless stuff" , "Rubbish, waste" , "Anything of poor quality" , "Take the tops from < rhubarb" .)
