When Djokovic wraps up, it's brilliant! (6)
I believe the answer is:
superb
'it's brilliant' is the definition.
(I've seen this before)
'when djokovic wraps up' is the wordplay.
I cannot quite understand how this works, but
'when' could be 'e' (I've seen this in other clues) and 'e' is present in the answer.
'up' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for superb that I've seen before include "Quite splendid, really excellent" , "Splendid, brilliant" , "Admirable" , "First-class" , "Tiptop" .)
