Loser idly curious, in a manner befitting a warrior (9)

I believe the answer is:

soldierly

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

'a manner befitting a warrior' is the definition.
I can't judge whether this defines the answer.

'loser idly curious' is the wordplay.
'curious' indicates anagramming the letters.
'loser'+'idly'='loseridly'
'loseridly' is an anagram of 'SOLDIERLY'.

'in' is the link.

Can you help me to learn more?
