Guardiola wins opening battle

Football EPL : City pip United 2-1 in Manchester derby; Spurs sparkle

Pep Guardiola rocked old foe Jose Mourinho as Premier League leaders Manchester City extended their perfect start with a 2-1 win over Manchester United, while Arsenal snatched a dramatic 2-1 victory against Southampton on Saturday.

City manager Guardiola inflicted the first defeat of Mourinho's United reign and collected his eighth win in 17 encounters with his nemesis in a pulsating encounter at Old Trafford.

Guardiola's side took the lead in a sweet moment of revenge for Kevin De Bruyne, acrimoniously sold by Mourinho when the pair were together at Chelsea, as the Belgium midfielder punished Daley Blind's miscue to slot past David de Gea in the 15th minute.

Kelechi Iheanacho doubled City's lead in the 36th minute when he tapped in after a De Bruyne shot hit the post and rebounded to the Nigeria forward.

A blunder from City's debutant goalkeeper Claudio Bravo allowed United to reduce the deficit in the 42nd minute when he dropped a cross and Zlatan Ibrahimovic pounced to lash home.

But City held firm in the second half despite more nervous moments from Bravo, whose studs-up lunge on Wayne Rooney could have drawn a penalty and a red card.

Although the Manchester derby overshadowed the rest of the day's action, there was plenty of drama elsewhere, including at the Emirates Stadium where Arsenal eased the pressure on Gunners boss Arsene Wenger.

Wenger, who gave debuts to Germany defender Shkodran Mustafi and Spanish forward Lucas Perez, has been questioned over his transfer dealings and Arsenal's slow start to the season.

The critics were sharpening their knives when Arsenal fell behind in the 18th minute through a Petr Cech own goal after Dusan Tadic's free-kick deflected off the goalkeeper.

But Arsenal equalised 11 minutes later thanks to a spectacular overhead kick from France defender Laurent Koscielny.

And Santi Cazorla secured Arsenal's second win of the season when the Spanish midfielder stroked home a controversial penalty awarded for Jose Fonte's tackle on Olivier Giroud in the 94th minute.

Tottenham swept to a 4-0 victory at bottom of the table Stoke as South Korea midfielder Son Heung-min sparkled on his first appearance of the season.

Watford staged a superb recovery to beat West Ham 4-2 and secure Italian manager Walter Mazzarri's first win since taking charge in the close-season. Bournemouth striker Callum Wilson secured his side's first win of the season as his clever backheeled finish in the 79th minute saw off West Bromwich Albion 1-0 at Dean Court.

Crystal Palace ended a three-match winless run as Christian Benteke's first goal for the club inspired a 2-1 success at Middlesbrough.

Liverpool win

Meanwhile, Roberto Firmino struck twice (13th , 89th minutes) while Sadio Mane (31st minute) and Adam Lallana (56th minute) netted a goal each as Liverpool drubbed premier league champions Leicester City 4-1. Jamie Vardy scored the only goal in the 38th minute for Leicester .
