Very exciting Scottish team — super! (5-8)

I believe the answer is:

heart-stopping

'very exciting' is the definition.
(heart-stopping means tense or exciting)

'scottish team super' is the wordplay.
'scottish team' becomes 'hearts' (nickname of Heart of Midlothian FC).
'super' becomes 'topping' (topping is old-fashioned slang for excellent).
'hearts'+'topping'='HEART-STOPPING'

(Another definition for heart-stopping that I've seen is " Frighteningly exciting".)

I've seen this clue in The Guardian.
