Praise opponent in speech when they get there (2,7)

Ross

I believe the answer is:

on arrival

I'm a little stuck... Click here to teach me more about this clue!

'get there' is the definition.
I can't tell whether this definition defines the answer.

'praise opponent in speech when they' is the wordplay.
I cannot quite see how this works, but
'opponent' could be 'rival' (a rival is an opponent or enemy) and 'rival' is located in the answer.
'when' could be 'on' (I've seen this in other clues) and 'on' is present in the answer.
The remaining letters 'ar' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
