These are very easy games with good odds, but since they're top teams against bottom teams, it's relatively easy to bet. But anything can happen at the start.
Can’t say for good odds but if the games were easy, I could go with that for Sporting CP. Didn’t start the game with them but, I joined up later in the first half and to have seen that they conceived an early go, I knew they would come back to win in the end. Though they played better in the first half, they couldn’t manage to get a goal but, the case was much more different in the second half. They got an early second half goal and after their second goal was disallowed in the second half, they soon figured out that the best way to beat the goalkeeper was to shoot from outside the box and soon got 4 goals all scored in the second half. It was a spectacle.
