Possible Italian tourist handbook with nothing for the English (5)

'possible italian tourist handbook' is the definition.
I know nothing about this answer so I can't judge whether this works.

'nothing for the english' is the wordplay.
'nothing' becomes 'O' (looks like zero - 0).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'the english' becomes 'guid' (I can't justify this - if you can you should give a lot more credence to this answer).
'o' after 'guid' is 'GUIDO'.

'with' is the link.

Can you help me to learn more?
