First I want to ask why I get no points for thursday (yesterday). I gave my comment 5½ hours before the first match starts and in rules stand: "Participations end before the first game starts (19:30 /7:30 pm UTC)." - can you please check, because I think I should get 6 points for thursday.
Now my prediction for Sunday:
1- Lazio vs Juventus: Under 2.5
2- Espanyol vs Real Madrid: Over 2.5
3- Paris SG vs Rennes: Over 2.5
