He's a saver (6)

Ross

I believe the answer is:

goalie

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

'a saver' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'he's' is the wordplay.
I cannot really see how this works, but
'he' could be 'ali' and 'ali' is found within the answer.
The remaining letters 'goe' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for goalie that I've seen before include "Soccer player who protects the target" , "number one" , "Keeper (colloq.)" , "Hart perhaps" , "On-field custodian" .)
