Admit us going round sports ground (7)
I believe the answer is:
stadium
'sports ground' is the definition.
(I've seen this before)
'admit us going round' is the wordplay.
'going round' is an anagram indicator.
'admit'+'us'='admitus'
'admitus' anagrammed gives 'STADIUM'.
(Other definitions for stadium that I've seen before include "bowl?" , "Venue for sporting events, concerts etc" , "A major sports ground" , "Sports ground as for athletics" , "Open-air sports venue" .)
