The big clash of the day was at Stamford Bridge, where Chelsea took on Manchester City.
Pep Guardiola's side started the game at a quick pace, as noted by ESPN FC's Liam Twomey:
Liam Twomey @liam_twomey
City are operating at a frantic pace with & without the ball. Hard to see Chelsea matching it for 90 minutes so soon after Atletico #cfc2017-9-30 16:47:57
However, there was an early blow for the champions as Alvaro Morata was forced off due to injury.
Football journalist Dan Levene said Morata may have picked up the problem in the midweek 2017/18 UEFA Champions League win over Atletico Madrid:

Morata limping post-match in Madrid. Willian readied for action remarkably quickly here. Suspect Conte knew it was a 30min fitness test.2017-9-30 17:23:47
Antonio Conte responded by sending on Willian, but with their top scorer missing, Chelsea offered little going forwards and City began to take control.
The visitors' dominance was such it was almost as if the Blues were a man down, according to James Robson at the Manchester Evening News:
James Robson @JamesRobsonMEN
Chelsea look like they're down to 10 men2017-9-30 17:45:04
It was therefore little surprise when City went ahead through Kevin De Bruyne's sweetly-struck left-footed shot from just outside the area
City could have had a second after Gabriel Jesus' sidefoot volley beat Thibaut Courtois, but defender Antonio Rudiger managed to block the shot on the goal line.
Chelsea rallied late on, but City saw them off comfortably on a bad night for the Blues, who are now six points off the top and must wait to see the extent of Morata's injury.
Meanwhile, Manchester United head into the international break unbeaten in the Premier League after handing Crystal Palace a seventh straight league defeat.
Roy Hodgson’s men are also still without a goal, and their poor start means they now share an unwanted record, per Opta:
7 - Crystal Palace are only the second team to lose their opening seven games in a @PremierLeague season, after Portsmouth in 2009-10. Woe.2017-9-30 15:55:21
Marcus Rashford assisted the goals for Mata and Fellaini before being replaced by Anthony Martial, who then set up Lukaku.
Stuart Mathieson of the Manchester Evening News feels Jose Mourinho is getting the best out of both players:
Stuart Mathieson @StuMathiesonMEN
The Martial vs Rashford scenario is bringing the best out of both of them. What a luxury for Mourinho #mufc2017-9-30 14:07:12
United have made a superb start to the season, but Mourinho's men will be tested to the full when the Premier League returns after the international break, as their next fixture is a trip to Anfield to face Liverpool.
Tottenham are just five points behind City and United after another big win, with striker Kane following up his midweek UEFA Champions League hat-trick with another two goals.
Football writer Liam Canning said there is no question the England international is a world-class player:
Liam Canning @LiamPaulCanning
Harry Kane is world-class. No debate about it. Goal after goal after goal.2017-9-30 11:54:39
Kane now has 11 goals for Spurs this season, with Ben Davies and Moussa Sissoko also on target as Mauricio Pochettino's men maintained their perfect record away from home this season.
Elsewhere there were wins for Stoke City and West Ham, while Watford rescued a point at West Brom thanks to a stoppage-time equaliser from Brazilian striker Richarlison, and Bournemouth held Leicester to a goalless draw.
