Goal at the start gets overturned stopping three points for reserves (4,4)
I believe the answer is:
nest eggs
'reserves' is the definition.
(I've seen this before)
'goal at the start gets overturned stopping three points' is the wordplay.
'at the start' says to take the initial letters.
'overturned' shows that the letters should be reversed in order.
'stopping' is an insertion indicator (inserted letters stop or plug a gap).
'three points' becomes 'nes' ().
The first letter of 'goal' is 'g'.
'g'+'gets'='ggets'
'ggets' back-to-front is 'stegg'.
'stegg' placed within 'nes' is 'NEST-EGGS'.
'for' is the link.
(Other definitions for nest eggs that I've seen before include "set aside funds" , "reserves" , "savings" , "funds providing financial security" .)
