Foreigners in thoroughfare in front of Glasgow club (9)
I believe the answer is:
strangers
'foreigners' is the definition.
(I've seen this before)
'thoroughfare in front of glasgow club' is the wordplay.
'thoroughfare' becomes 'st' (I've seen this in other clues).
'in front of' is a charade indicator (letters next to each other).
'glasgow club' becomes 'rangers' (I can't explain this - if you can you should give a lot more credence to this answer).
'st'+'rangers'='STRANGERS'
'in' is the link.
Can you help me to learn more?
(Other definitions for strangers that I've seen before include "Aliens" , "Foreigners" , "Outsiders" , "Those we have not met" , "People one doesn't know" .)
