German designer picked up drink knocked over (9)

I believe the answer is:

lagerfeld

'german designer' is the definition.
(I know that Lagerfeld is German)

'picked up drink knocked over' is the wordplay.
I cannot really see how this works, but
'drink' could be 'lager' (lager is a kind of drink) and 'lager' is located in the answer.
This explanation may well be incorrect...

I've seen this clue in The Guardian.
