God of love heading for disaster at home (4)
I believe the answer is:
odin
'god' is the definition.
(Odin is an example)
'love heading for disaster at home' is the wordplay.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'heading for' indicates taking the first letters.
'at home' becomes 'in' ('in' can be similar in meaning to 'at home').
The initial letter of 'disaster' is 'd'.
'o'+'d'+'in'='ODIN'
'of' acts as a link.
(Other definitions for odin that I've seen before include "King of Norse gods" , "The supreme Norse god and creator" , "Pagan god" , "Supreme Norse deity" , "Supreme god of war in Norse mythology" .)
