Sharp, visible illegal tackle to get rid of ball (10)

I believe the answer is:

insightful

'sharp' is the definition.

'visible illegal tackle to get rid of ball' is the wordplay.
'visible' becomes 'insight' ('in sight' can be similar in meaning to 'visible').
'illegal tackle' becomes 'foul'.
'to get rid of' is a deletion indicator.
'ball' becomes 'o'.
'foul' with 'o' removed is 'ful'.
'insight'+'ful'='INSIGHTFUL'

(Another definition for insightful that I've seen is " penetrating".)

I've seen this clue in The Guardian.
