I believe the answer is:

on and on

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

'constantly' is the definition.
(thesaurus)

'working with side at old trafford?' is the wordplay.
'working' becomes 'on'.
'with' becomes 'and'.
'side at old trafford?' becomes 'on' (I am not sure about this - if you are sure you should believe this answer much more).
'on'+'and'+'on'='ON AND ON'

Can you help me to learn more?

(Other definitions for on and on that I've seen before include "Incessantly" , "Ever" , "continuously" , "Unceasingly" , "Endlessly" .)

I've seen this clue in The Telegraph.
