Fans of Reading FC maybe with caution in the first place (4,4)
I believe the answer is:
book club
'fans of reading fc' is the definition.
I know that 'reading' relates to this answer.
'with caution in the first place' is the wordplay.
'with' says to put letters next to each other.
'caution' becomes 'book' (a footballer receiving a yellow card gets 'booked').
'in the first place' becomes 'club' (I am not sure about this - if you are sure you should believe this answer much more).
'book'+'club' is 'BOOK CLUB'.
'maybe' is the link.
Can you help me to learn more?
(Other definitions for book club that I've seen before include "Lit. Soc." , "Literary group" , "literary gathering" , "Society giving members cheaper access to reading material" , "Society for readers" .)
