Just had a brief look:
2020-21, two goals against by former players (Kosta x2)
2021-22, four goals against by former players (Hemed x2, Uli, Rojas)
2022-23 already seven goals against by former players (McGarry x2, Tratt, David Williams x3, Uli)

Don't need to worry about Davila scoring against us twice this season though when we vs Macarthur again as he's unfortunately been ruled out for the rest of the season with a knee injury.
There's also Victory (Bozinovski) but I think it's unlikely.
