Bury with one manager, initially caretaker (7)
I believe the answer is:
interim
'caretaker' is the definition.
(I've seen this before)
'bury with one manager initially' is the wordplay.
'bury' becomes 'inter' (to inter is to put into the ground).
'with' says to put letters next to each other.
'one' becomes 'i' (Roman numeral).
'initially' indicates taking the first letters.
The first letter of 'manager' is 'm'.
'inter'+'i'+'m'='INTERIM'
(Other definitions for interim that I've seen before include "Meantime; temporary" , "Meanwhile" , "Stopgap" , "Temporary - provisional" , "Caretaker" .)
