'the ultimate defender of clean sheets' is the definition.
I can't tell whether this definition defines the answer.

'where to be' is the wordplay.
I cannot quite understand how this works, but
'be' could be 'go' (going is a kind of being) and 'go' is located in the answer.
This explanation may well be incorrect...

Can you help me to learn more?
