Je nachdem, was man betonen will.

Place the word only directly in front of the word it modifies.

As a general rule if you are stuck, stick to "he only has"

I hear too many Germans using "he has only" and getting it wrong. That's not to say it is wrong at all - of course it isn't - but it can only be used in specific circumstances.

@Markus, if you would only provide us with a longer sentence, er, if only you would provide us with a longer sentence.

Can you? Peace
