Mates before Saturday begins? (7)

Ross

I believe the answer is:

friends

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

'mates' is the definition.
The definition and answer can be both people as well as being plural nouns.
Maybe there's an association between them I don't understand?

'before saturday begins?' is the wordplay.
I cannot really see how this works, but
'saturday' could be 's' and 's' is found within the answer.
The remaining letters 'friend' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for friends that I've seen before include "Intimates" , "Chums" , "Intimate acquaintances" , "Pals, comrades" , "playmates!" .)

I've seen this clue in The Guardian.
