Bloc removed from Barcelona stadium (5)

I believe the answer is:

arena

'stadium' is the definition.
(eg a sports arena)

'bloc removed from barcelona' is the wordplay.
'removed from' suggests deleting specific letters.
'barcelona' with 'bloc' taken away is 'ARENA'.

(Other definitions for arena that I've seen before include "Space for public events" , "park" , "Performance space" , "Place of combat" , "Ring for contest" .)

I've seen this clue in the Sydney Morning Herald.
