One who bargains on a tiger to be tamed (10)

I believe the answer is:

negotiator

'one who bargains' is the definition.

'on a tiger to be tamed' is the wordplay.
'be tamed' indicates anagramming the letters.
'on'+'a'+'tiger'+'to'='onatigerto'
'onatigerto' is an anagram of 'NEGOTIATOR'.

(Other definitions for negotiator that I've seen before include "One trying to agree a compromise" , "One may circumvent obstacles" , "One making deal" , "One in discussions to reach an agreement" , "Bargaining type" .)

I've seen this clue in The Guardian.
