United, with excellent scoring shot, back in the perfect place to be (6)
I believe the answer is:
utopia
'the perfect place to be' is the definition.
(a utopia is a perfect place)
'united with excellent scoring shot back' is the wordplay.
'united' becomes 'u'.
'with' means one lot of letters go next to another.
'excellent' becomes 'ai'.
'scoring shot' becomes 'pot' (a snooker shot where a player pots a ball).
'back' says the letters should be written backwards.
'ai'+'pot'='aipot'
'aipot' written backwards gives 'topia'.
'u'+'topia'='UTOPIA'
'in' acts as a link.
(Other definitions for utopia that I've seen before include "Supposed ideal land" , "Place of perfect happiness" , "Thomas More's perfect society" , "Sir Thomas Moore's perfect society" , "place of bliss" .)
