Centre half in home game is fab (4)
I believe the answer is:
mega
'centre half' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'home game is fab' is the wordplay.
'game' can be anagrammed to 'MEGA'.
But, I'm not sure how this is indicated.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for mega that I've seen before include "Fantastic!" , "Very large (colloq.)" , "wicked" , "As brilliant" , "Terrific" .)
