How do you say "Have you already filled in a E(uropean) C(hampionship) pool?" in Italian? A pool is a piece of paper on which you can fill in your prediction about the winners and scores of the soccer championship, which is mostly handed in for money. If your prediction is the best, you win (part of) the money people have given to participate. Oh yeah, my guess: "hai riempito un piatto per il ...(cec? Campionato europeo di calcio?)"?
