What happened in the Premier League? Wins for Man City, Tottenham, Burnley and Brighton
Manchester City began their quest for a third successive Premier League title with a resounding win at West Ham in a game that saw the video assistant referee play a significant role.
VAR, introduced to the Premier League for the first time this season, was used several times as Raheem Sterling scored a hat-trick while Gabriel Jesus and Sergio Aguero, from a retaken penalty, also netted in a 5-0 victory for the champions.
Harry Kane twice struck late as Tottenham overcame resilient Aston Villa 3-1 at the Tottenham Stadium. Spurs, who finished fourth last season, fell behind to a ninth-minute John McGinn goal before they equalised courtesy of a brilliant strike from their £53m club-record signing Tanguy Ndombele.
Kane, who scored 17 league goals last season, fired in two goals in the final four minutes to earn Tottenham an opening weekend victory.
Sheffield United, who were playing in League One as recently as 2017, marked their return to the Premier League after a 12-year absence with a spirited 1-1 draw at Bournemouth, Billy Sharp scoring an 88th-minute equaliser to cancel out Chris Mepham's first goal for the Cherries.
Everton's Morgan Schneiderlin was sent off in the 76th minute, while Wilfried Zaha started on Palace's bench after missing out on a move before the summer transfer deadline.
Brighton, who finished two points above the relegation zone last season, got off to a flying start under new boss Graham Potter.
They won 3-0 at last season's FA Cup runners-up Watford - an own goal by Abdoulaye Doucoure, plus strikes by Florin Andone and new signing Neal Maupay sealing the points.
Burnley also won 3-0 at home to Southampton, Ashley Barnes with two goals and Johann Berg Gudmundsson the other.
There are three games on Sunday, including Manchester United against Chelsea at Old Trafford (16:30) in Frank Lampard's first league match in charge of the Blues.
Before that, Newcastle entertain Arsenal (14:00) at the same time as Wolves play at Leicester.
