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

'arsenal's no 1 policy to keep current manager ultimately in emirates?' is the definition.
I can't judge whether this definition defines the answer.

'arsenal's no 1 policy to keep current manager ultimately' is the wordplay.
'arsenal's no 1' becomes 'a' (1st letter of 'arsenal').
'policy' becomes 'line' (I've seen this before).
'to keep' means one lot of letters goes inside another.
'current' becomes 'I' (symbol for electric current).
'ultimately' suggests the final letters.
The last letter of 'manager' is 'r'.
'a'+'line'='aline'
'i'+'r'='ir'
'aline' going around 'ir' is 'AIRLINE'.

Can you help me to learn more?

(Other definitions for airline that I've seen before include "Company providing scheduled flights" , "BA, say" , "EasyJet, for example" , "SAS perhaps" , "Qantas, for example" .)
