I just checked the fixture. The opening week is actually pretty good. Arsenal will play away game with Manchester United. It'll be a good test right at the start of the season. Arsenal have been dominating Manchester United for quite some time. Last season Manchester United were already very poor. They lost almost half of their matches. This time they'll want to start with a clean slate.
I think Manchester City will beat Wolverhampton easily. Spurs will also win probably. As for Liverpool and Chelsea, I'm not so sure though.
Time flies so quickly, and the new Premier League season is just around the corner. Meanwhile, regarding the opening week's matches, the match between Manchester United and Arsenal will be the most exciting. On paper, Arsenal are certainly favored to win, even though Manchester United will be the host. Furthermore, the Aston Villa versus Newcastle match is also worth anticipating, because both teams have almost equal strength.
In theory, Liverpool, Manchester City, Chelsea, and Tottenham are also likely to secure three points in their respective opening matches. However, surprises could still happen, considering the squad overhauls carried out by almost all the contenders. Pre season tour matches may be useful in predicting the outcome.
