Smarmy new goalie with talent ... (10)
I believe the answer is:
oleaginous
'smarmy' is the definition.
(I know that smarmy can be written as oleaginous)
'new goalie with talent' is the wordplay.
'new' is an anagram indicator.
'with' says to put letters next to each other.
'talent' becomes 'nous' (nous or common sense is a type of talent).
'goalie' anagrammed gives 'oleagi'.
'oleagi'+'nous'='OLEAGINOUS'
(Other definitions for oleaginous that I've seen before include "fawning" , "oily" .)
