Sheepish face of goalie, intercepting pass with defensive blunder (7)
I believe the answer is:
hangdog
'sheepish' is the definition.
(I've seen this before)
'face of goalie intercepting pass with defensive blunder' is the wordplay.
'face of' suggests taking the first letters.
'intercepting' is an insertion indicator (I've seen this in other clues).
'pass' becomes 'hand' ('hand' can be a synonym of 'pass'**).
'with' says to put letters next to each other.
'defensive blunder' becomes 'og' (own goal, football blunder).
The initial letter of 'goalie' is 'g'.
'g' placed into 'hand' is 'hangd'.
'hangd'+'og'='HANGDOG'
(Other definitions for hangdog that I've seen before include "Appearing ashamed" , "Cowed, furtive" , "Looking embarrassed" , "Having a guilty appearance, shamefaced" , "Guilty-looking" .)
