Milan struggled to follow negative token (7)
I believe the answer is:
nominal
'token' is the definition.
(I know that token can be written as nominal)
'milan struggled to follow negative' is the wordplay.
I cannot quite see how this works, but
an anagram of 'milan' is 'minal' which is located in the answer.
'negative' could be 'no' (no is a kind of negative) and 'no' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for nominal that I've seen before include "Inconsiderable" , "Minor" , "trifling" , "not real" , "In name only or of token value (7)" .)
