Winning over Spain is painless: centre for training is lacking (9)

I believe the answer is:

seduction

'winning over' is the definition.
(seduce can mean to win someone over)

I can't explain the rest of the clue.

(Other definitions for seduction that I've seen before include "Allure" , "sexual temptation" , "Deceptive activity" .)

I've seen this clue in The Times.
