'carefully confront a' is the definition.
I can't judge whether this defines the answer.

'confused liar in outer wembley' is the wordplay.
'confused' indicates an anagram.
'in' is an insertion indicator.
'outer' suggests removing the centre.
'wembley' with its centre taken out is 'wy'.
'liar' anagrammed gives 'aril'.
'aril' put into 'wy' is 'WARILY'.

Can you help me to learn more?
