'noisome casanova' is the definition.
(character in the Looney Tunes cartoons)

'footballer on page keen to read up about it' is the wordplay.
'footballer' becomes 'pele' (Brazilian footballer Pele).
'on page' becomes 'p' (I am not sure about the 'on' bit.).
'keen' becomes 'weep' (I've seen this before).
'to read up' shows that the letters should be reversed in order (I've seen 'reading up' mean this (in a down clue, letters go up)).
'about it' is an insertion indicator.
'weep' in reverse letter order is 'peew'.
'pele'+'p'='pelep'
'pelep' going into 'peew' is 'PEPE LE PEW'.
