Superhuman Olympians seen around the centre of Milan: what do they want? (5)

'do they want?' is the definition.
Although both the answer and 'do' are nouns, they are not in the same form of the noun.

'superhuman olympians seen around the centre of milan' is the wordplay.
'superhuman olympians' becomes 'gods' (I've seen this in another clue. I am not sure about the 'superhuman' bit.).
'seen around' means one lot of letters goes inside another.
'the centre of' means to look at the middle letters.
The middle letter of 'milan' is 'l'.
'gods' enclosing 'l' is 'GOLDS'.

'what' is the link.
