Personal appeal from Messi in the middle after pass: "Really, guys?" (12)

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

'messi in the middle after pass really guys?' is the wordplay.
'in the middle' means to look at the middle letters.
'after' says to put letters next to each other.
'pass' becomes 'hand' (synonyms).
'really' becomes 'so' (both can mean 'extremely').
'guys?' becomes 'men' (guy can mean a man).
The central letters of 'messi' are 'ess'.
'hand'+'so'+'men'='handsomen'
'ess' after 'handsomen' is 'HANDSOMENESS'.

'from' is the link.
