Wild financier finally not in favour of investing in soccer team (7)
I believe the answer is:
frantic
'wild' is the definition.
('frantic' can be similar in meaning to 'wild')
'financier finally not in favour of investing in soccer team' is the wordplay.
'finally' indicates one should take the final letters.
'not in favour of' becomes 'anti' (I've seen this before).
'investing in' means one lot of letters goes inside another.
'soccer team' becomes 'fc' (football club).
The last letter of 'financier' is 'r'.
'r'+'anti'='ranti'
'ranti' going into 'fc' is 'FRANTIC'.
(Other definitions for frantic that I've seen before include "very worried" , "Beside oneself" , "having kittens" , "Berserk" , "Deranged by fear, worry etc" .)
