Near a new stadium (5)
I believe the answer is:
arena
'stadium' is the definition.
(eg a sports arena)
'near a new' is the wordplay.
'new' is an anagram indicator.
'near'+'a'='neara'
'neara' is an anagram of 'ARENA'.
(Other definitions for arena that I've seen before include "centre of conflict" , "O2, for example" , "Area of combat" , "Engagement ring" , "Venue for contests" .)
