Love cricket club to capture trophy, an ultimately quality possession (9)
I believe the answer is:
occupancy
'possession' is the definition.
(I've seen this before)
'love cricket club to capture trophy an ultimately quality' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'cricket club' becomes 'cc' (cricketing abbreviation).
'to capture' is an insertion indicator.
'trophy' becomes 'cup' (cup is a kind of trophy).
'ultimately' suggests the final letters.
The final letter of 'quality' is 'y'.
'cup'+'an'='cupan'
'cc' placed around 'cupan' is 'ccupanc'.
'o'+'ccupanc'+'y'='OCCUPANCY'
(Other definitions for occupancy that I've seen before include "Tenure" , "Tenancy" , "The proportion of a hotel in use" , "possession" , "Residence" .)
