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.
Manchester United against Arsenal should be a draw result in my opinion. The last six months been used to gather enough information for the new season. I don't really care about the first five games we play, I just want to see us in the top four at the end of the season. I'm also looking up to the game between Crystal Palace and Chelsea. They should be fatigued enough to let Chelsea cruise pass them in my opinion.
The rivalry between the two teams is always a highlight of the match between Manchester United vs Arsenal considering that both teams have balanced strengths in various lines, I think MU has the advantage of playing at home, the physical and mental readiness of the players will greatly affect their performance on the field, especially in high-intensity matches, and also the tactics implemented by the coaches of each team will also be key in determining the final result of the match. I think Chelsea does not want to be left behind with an above-average advantage over their opponents, of course Chelsea will take this golden opportunity to pick up three points at their opponent's home to top the standings.
