I've always thought the 'agreed' personal terms BS for most big transfers in more like a general understanding of what terms would be over many different areas.
I would imagine it is different from knowing he wants X per week, it's more like knowing appearance money, image rights, etc. so the Agent tells us informally so we can prepare what these days is a very detailed contract. In this sense I take it to mean 'agreed what terms would be personable' rather than personal terms per se.
Maybe I've no clue whatsoever
