Copper has pressure to get trophy (3)
I believe the answer is:
cup
'trophy' is the definition.
(cup is a kind of trophy)
'copper has pressure' is the wordplay.
'copper has' becomes 'cu' (I've seen this in other clues).
'pressure' becomes 'p' (abbreviation).
'cu'+'p'='CUP'
'to get' is the link.
(Other definitions for cup that I've seen before include "Beaker" , "Trophy, drink" , "Drinking bowl" , "Prize; vessel" , "Container to drink from - prize" .)
