Some Penguin 'Football Facts' (4)
I believe the answer is:
info
'facts' is the definition.
(thesaurus)
'some penguin football' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'INFO' can be found hidden inside 'penguin football'.
(Other definitions for info that I've seen before include "Data received and understood (abbr)" , "What's known" , "Dope" , "News" , "Data (abbrev.)" .)
