At least the wait is over, it's being boring that most weekends is not as fun as it used to be, in as much as the club world cup brought a little spice to the football world but it's still not as fun like the league whereby you will go to the viewing center with the intention of bantering with Manchester united and Chelsea fan, but since it's back, the fun is back.
Talking about this your bet here, Liverpool and Chelsea are obviously going to win, but I wouldn't be taking this Manchester united vs arsenal game because their are more better matches to bet on, that are more clearer than this game, but their is a higher probability that they can play according to how you want them to be, which is both teams to score.
The Aston villa game vs Newcastle is also going to be an interesting encounter which their is a probability that they might score themselves, but I wouldn't be going with such option either, I prefer going with over 2.5 than both teams to score.
