With space to move, Bale's dribbling worth utilising (10)

Ross

I believe the answer is:

employable

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

'dribbling worth utilising' is the definition.
I can't tell whether this defines the answer.

'with space to move bale's' is the wordplay.
'with' is an insertion indicator.
'space' becomes 'employ' (I can't explain this - if you can you should believe this answer much more).
'to move' indicates an anagram (I've seen 'moves' mean this).
'bale' with letters rearranged gives 'able'.
'employ' put within 'able' is 'EMPLOYABLE'.

Can you help me to learn more?

(Another definition for employable that I've seen is " that may be used".)

I've seen this clue in The Independent.
