Goal scoring goalkeeper scoring a hat trick, in an European final no less. Crazy and awesome. Makes me wonder if anyone has actually ever done it in real life.
You really make me think about doing the goal scoring goalkeeper myself.
Edit: Well, after googling, apparently José Luis Chilavert did it for Vélez Sarsfield. Rogério Ceni apparently scored two penalties, and saved a penalty in the same match.
There are instances of few other goalkeepers scoring a hat-trick but they were playing as an outfield players at that moment, for various reasons.
