'enthusiasm for liverpool players' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'lively neat amiable?' is the wordplay.
'lively' indicates an anagram (letters get livened up or moved around).
'neat'+'amiable'='neatamiable'
'neatamiable' anagrammed gives 'BEATLEMANIA'.
