Estadio cheer (3)
I believe the answer is:
ole
'estadio cheer' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ole that I've seen before include "Hurrah in Spain" , "Hurry in Spain" , "Well done! (Span.)" , "Bravo (Spanish)" , "Hooray in Spain" .)
