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.
I just checked their head2head record in their last five games, truly arsenal are the most dominant side because they have won three out of five, while Manchester united has won only once and they drew once, but if I were to stake on this game, I will be going for a score draw because arsenal will be playing away from home and am confident that due to the fact that it's the first game of the season, Manchester united will do everything in their power not to lose this game, that's why I believe that the game is going to end in a draw.
Then as for the rest of other top teams, they are all going to win in my own opinion because they will want to prove a point in this first game of the season, but they are all going to be a fascinating contest if their is no controversial red card in any of these games.
