One may go to pot, seeing most of side on reserve (6)

Ross

I believe the answer is:

teabag

'one may go to pot' is the definition.
(as in a teapot)

'most of side on reserve' is the wordplay.
'most of' means to remove the last letter.
'side' becomes 'team' (I've seen this before).
'on' means one lot of letters go next to another.
'reserve' becomes 'bag'.
'team' with its last letter taken away is 'tea'.
'tea'+'bag'='TEABAG'

'seeing' acts as a link.

(Another definition for teabag that I've seen is " drink maker".)

I've seen this clue in The Telegraph.
