Girl receiving ball shows intention (4)
I believe the answer is:
goal
'intention' is the definition.
(I've seen this in another clue)
'girl receiving ball' is the wordplay.
'girl' becomes 'gal'.
'receiving' means one lot of letters goes inside another.
'ball' becomes 'o' (O looks like a ball).
'gal' placed around 'o' is 'GOAL'.
'shows' is the link.
(Other definitions for goal that I've seen before include "Football score" , "Target or ambition" , "Soccer achievement" , "Aim (at football)" , "Aim or purpose" .)
