London: High-flying Southampton thrashed Sunderland 8-0 in the Premier League on Saturday as unbeaten leaders Chelsea remained five points clear at the top with a 2-1 win away to Crystal Palace.
Sergio Aguero scored all Manchester City's goals in a 4-1 defeat of 10-man Tottenham Hotspur as the champions remained second while Arsenal needed a stoppage-time equaliser to seal a 2-2 draw with Hull City -- the team they beat in last season's FA Cup final.
Everton climbed up the table with a 3-0 win at home to Aston Villa, and at the bottom Newcastle United won for the first time in the Premier League this season, beating Leicester City 1-0, but struggling Burnley remained winless after a 3-1 loss to visitors West Ham United.
At St Mary's, Southampton were 3-0 up at half-time, the goal rush starting when Sunderland's Santiago Vergini put through his own net when he volleyed in an attempted clearance in the 12th minute.
Graziano Pelle made it 2-0 six minutes later and there was more misery for the more than 2,000 travelling Sunderland fans who had made the long journey down from the north-east to the south coast when Jack Cork turned in from close range.
The goals kept coming in the second half, Liam Bridcutt diverting Pelle's shot into his own net for a second own goal of the match before Pelle, Dusan Tadic, Victor Wanyama and Sadio Mane piled on the agony for Sunderland as Southampton recorded their biggest top-flight victory in their history.
At Selhurst Park, Oscar's brilliant 30-yard free-kick gave Chelsea a sixth-minute lead, but five minutes before the break, Chelsea defender Cesar Azpilicueta was shown a red card for diving in two-footed on Mile Jedinak.
However, there was still time in the first half for Palace to also be reduced to 10 men, with Damien Delaney dismissed for a second bookable offence after hauling back Loic Remy.
Chelsea doubled their lead in the 51st minute when Cesc Fabregas played a one-two with Eden Hazard and Oscar before calmly planting the ball past Julian Speroni at the near post, before Palace pulled a goal back in the last minute of normal time through Fraizer Campbell.
Aguero was the star turn as Manchester City overwhelmed Spurs, who last season conceded 11 goals in two league games against the eventual champions.
The Argentina forward opened the scoring in the 13th minute and then struck from the penalty spot seven minutes later after Christian Eriksen's 15th-minute equaliser.
Aguero missed a chance to seal his hat-trick before half-time when his second penalty was saved by Hugo Lloris.
Referee Jon Moss awarded the third penalty of the match in the 62nd minute when Martin Demichelis tripped Tottenham's Roberto Soldado, with replays indicating the offence took place outside the penalty area.
However, Spanish striker Soldado fluffed the chance to equalise as his spot-kick was saved by Joe Hart.
Moss gave his fourth penalty in the 68th minute when Federico Fazio pulled back Aguero, a foul that also earned the Argentine defender a red card on his Premier League debut.
Aguero, who is now City's record scorer in the Premier League era, stroked home the penalty and sealed the one-man demolition job with another clinical strike to make it four in the 75th minute.
Alexis Sanchez's powerful shot put Arsenal ahead in the 13th minute at the Emirates Stadium before Mohamed Diame levelled for Hull minutes later.
Hull went ahead early in the second half when Abel Hernandez headed home Tom Huddlestone's cross and it seemed the Tigers would hold on for victory until England forward Danny Welbeck struck in stoppage time.
West Ham gave manager Sam Allardyce the perfect present ahead of his 60th birthday on Sunday with victory at Burnley that took them into the top four.
Diafra Sakho's sixth goal in as many games gave West Ham the lead in the 49th minute and Enner Valencia made it 2-0 five minutes later.
George Boyd pulled one back on the hour mark before Hammers substitute Carlton Cole put the result beyond doubt.
Everton saw off Villa at Goodison Park thanks to goals from captain Phil Jagielka, Romelu Lukaku and Seamus Coleman.
At St James' Park, kick-off was delayed by an hour after repairs had to be made to one of the giant television screens, dislodged by strong winds. But the wait was worthwhile for Newcastle's long-suffering fans when Gabriel Obertan's 71st-minute goal sealed a desperately-needed victory.
