Team heading for Wembley maybe FA are inclined to keep at home (8)
I believe the answer is:
finalist
'team heading for wembley maybe' is the definition.
(eg the FA Cup final is played at Wembley)
'fa are inclined to keep at home' is the wordplay.
'are inclined' becomes 'list' ('list' can mean to lean or tilt).
'to keep' means one lot of letters goes inside another.
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'fa'+'list'='falist'
'falist' placed around 'in' is 'FINALIST'.
(Other definitions for finalist that I've seen before include "One has reached the last round" , "He qualified" , "Winner of semi-final" , "Participant in the last round of a competition" , "Sportsman who gets into the last round" .)
