Abrasive meeting of Premier League manager and directors? (5,5)

I believe the answer is:

emery board

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

'abrasive' is the definition.
(I've seen this before)

'meeting of premier league manager and directors?' is the wordplay.
'meeting of premier league manager' becomes 'emery' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'and' is a charade indicator (letters next to each other).
'directors?' becomes 'board' (board of directors).
'emery'+'board'='EMERY BOARD'

Can you help me to learn more?

(Another definition for emery board that I've seen is " Abrasive".)

I've seen this clue in The Times.
