Manchester City are fortunate to hold onto their Premier League lead after glancing a 2-1 win over Norwich City in Week 11, while Arsenal defeated Swansea City 3-0 to stay level on points at the English summit.The Citizens were one of only two home teams to win their game on Saturday, but Everton defended Goodison Park's borders with a 6-2 thumping of Sunderland on Sunday to dampen the Black Cats' survival crusade.That result came before Southampton defeated Bournemouth 2-0 in the first south-coast derby ever played between the two teams in the top flight.Both the Toffees and the Saints sit just outside the top six thanks to their Week 11 victories, with the latest standings detailed ahead, complete with a roundup of all this weekend's fixtures.RecapAn Arouna Kone-inspired performance saw Everton trounce Sunderland 6-2 on Sunday in what was their first Premier League win since September, with the former Wigan frontman bagging a hat-trick.Romelu Lukaku and Gerard Deulofeu were also on the scoresheet while Sunderland's Sebastian Coates helped out with an own goal, and BBC Sport's Oluwashina Okeleji confirmed it was a special day for Kone, too:The victory moves the Toffees up to ninth, just one point and one place behind Merseyside rivals Liverpool, while the Black Cats are just two points off the bottom after failing to build on their win over Newcastle United.Manager Sam Allardyce is still getting used to his surroundings at the Stadium of Light, but is only too aware of the challenge that awaits him, pertheMirror's Tyrone Marshall:The defensive frailties were just too much in the side today and we allowed Everton to win the game comfortably in the end.If we dont sort those out, and we are going to give it away like we did when we get to 2-2 today, it will be a long haul over the next few months or so.We'll have to have a look into it. We've not played too bad in the first half.We got back to 2-2 but we just made it so easy for Everton to score three in seven minutes.From an attacking point of view we've got at Everton's back players and produced an awful lot of shots at their goal, but out of possession to let them score six from eight shots on target shows the frailties we've got.Last week's 3-0 win over the Magpies was Sunderland's first clean sheet of the season, and the northeast outfit don't appear any closer to a second based on Sunday's display.Meanwhile, Everton can hope this sparks some winning form after going four games without a victory, and the attacking pair of Lukaku and Kone looked particularly promising once again in Week 11.Later on Sunday, the 10 men of Southampton made Premier League history after beating Bournemouth2-0at St Mary's, the first ever Premier League meeting between the two local rivals.Steven Davis and Graziano Pelle provided the goals before Victor Wanyama was sent off 12 minutes from time for a second yellow, butMatch of the Day's Gary Lineker looked past that sour turn:Superior goal difference means Ronald Koeman's men climbed to seventh place and have now gone seven games without a defeat across all competitions.Much of that recent success has been thanks to the lively form of striker Pelle in front of goal, whom ESPN FC's Jake Cohen indicated is enjoying a bump in form late in his career:The Saints have suffered just two defeats in the Premier League this season, with only Leicester City and Tottenham Hotspur, both among the top six, able to boast fewer.Bournemouth remain just a point off the relegation zone, and their attacking threat has diminished drastically in the wake of numerous injuries, netting just four goals in their last six games.It was a fruitful weekend for both Merseyside powerhouses, after Jurgen Klopp defeated Chelsea 3-1 at Stamford Bridge on Saturday to claim his first Premier League victory as Reds chief.His side fell behind to a Ramires header after just four minutes, but Klopp was proud of his team's reaction as a Philippe Coutinho double was aided by a third from Christian Benteke to seal all three points:Blues manager Jose Mourinho may well consider his title defence well and truly over at this early stage, and the manager's position at Stamford Bridge is under even more scrutiny in the wake of Saturday's loss.It was almost a case of doom and gloom for Manuel Pellegrini's Citizens were Yaya Toure not on hand to slot home an 89th-minute penalty and cap off a 2-1 win over Norwich City, where the leaders looked turgid at times.Canaries striker Cameron Jerome cancelled out a Nicolas Otamendi header with seven minutes remaining, but Russell Martin blocked a late shot with his arm to give Toure the winning opportunity, which he took with some glee.Tight on their heels comes Arsenal, though, who survived without injured pair Theo Walcott and Alex Oxlade-Chamberlain to beat Swansea 3-0. Joel Campbell was among the scorers in his first Gunners start and told the club's official website what the result meant to him:Im very happy. I had to wait for this moment and now we have to keep working to strengthen our team.Im very happy but the important thing is the team wins. We had a good game so we have to keep going and prepare for the next game against Bayern Munich.The fans were incredible. They supported us the whole game and it was very important for us.Manchester United were unable to keep up the pace at the top after running to a bore draw at Crystal Palace, but the same can't be said for Leicester City, who hit back from a goal down to beat West Bromwich Albion 3-2.Riyad Mahrez bagged a brace while Jamie Vardy scored in his eighth successive league match as the Foxes moved into third, sitting just three points off the top after 11 games this season.West Ham United's unbeaten streak came to an end after they succumbed to a 2-0 loss at Watford, where Odion Ighalo was the Hornets' hero, scoring two for the north London hosts.And after failing to score in their defeat Sunderland, Newcastle were once again muted in a 0-0 draw at home to Stoke City, the Potters' first stalemate of the season.
