decider

I'm a little stuck... Click here to teach me more about this clue!

'golden goal' is the definition.
'decider' can be an answer for 'goal' (I have seen 'Ultimate goal' mean 'decider' so perhaps 'goal' could also mean 'decider'). I'm not sure about the 'golden' bit.

'half the side cried wildly' is the wordplay.
'half the' suggests halving the letters.
'wildly' is an anagram indicator.
'side' with half the letters taken is 'de'.
'cried' anagrammed gives 'cider'.
'de'+'cider'='DECIDER'

'for a' is the link.

Can you help me to learn more?

(Other definitions for decider that I've seen before include "It settles an outcome" , "It settles the matter" , "Important match" , "Ultimate goal" , "Extra period of play to settle a draw" .)
