A review of Saturday's action in the Barclays Premier League.
Jose Mourinho suffered his first defeat in his second coming as Chelsea manager as Everton's birthday boy Steven Naismith celebrated his first league start of the season in perfect fashion with the only goal.
The Scotland international, who scored in the 2-1 defeat at Stamford Bridge on the final day of the season when he was last in a Premier League starting line-up, headed home the winner from close range in first-half added time.
His goal also kick-started the Roberto Martinez era at Goodison Park after three successive draws had left the Spaniard with some convincing still to do.
Aaron Ramsey's second-half double snatched the points for Arsenal at the Stadium of Light but the game hinged on a controversial disallowed effort from Sunderland striker Jozy Altidore.
Altidore thought he had equalised for the Black Cats when he bundled the ball over the line in the 70th minute, only for referee Martin Atkinson to haul back the action and give the home side a free-kick for an earlier foul by Bacary Sagna.
Three minutes later Ramsey was sent through by Olivier Giroud at the other end to wrap up a 3-1 win for the Gunners.
Arsene Wenger's men dominated the first half but only had Giroud's 11th-minute opener to show for it after the Sunderland defence was carved open by impressive £42.5million debutant Mesut Ozil.
Craig Gardner brought the hosts level from the penalty spot after a foul by Laurent Koscielny on Adam Johnson two minutes into the second half, then Steven Fletcher had an effort ruled out for offside.
Ramsey put Arsenal back in front with a superb volley in the 67th minute, before Atkinson's controversial intervention sealed Sunderland's fate.
Eriksen combined with Roberto Soldado to set up the opener for Gylfi Sigurdsson in the 26th minute, and the Iceland international made it 2-0 from close range four minutes into the second half after a Paulinho cross.
The hosts had the best chances with Jon Walters heading a simple chance wide from a Geoff Cameron cross, then Kenwyne Jones forced a save out of Joe Hart after a mistake by Samir Nasri.
Jones headed just over early in the second half as Mark Hughes' men continued to look more likely to break the deadlock against his former club.
City's neighbours Manchester United had no such problems in the early kick-off against 10-man Crystal Palace, with goals from Robin van Persie and Wayne Rooney earning them a 2-0 win.
Watched by former boss Sir Alex Ferguson, Van Persie put United in front with a penalty in first half injury-time after Kagisho Dikgacoi was sent off for a foul on Ashley Young in the box.
New signing Marouane Fellaini came off the bench to make his United debut for the last half-hour, but it was Rooney who made the game safe with a superb 81st-minute free-kick.
Hatem Ben Arfa had given Alan Pardew's men an 18th-minute lead but Christian Benteke's powerful 67th-minute header drew Villa level and left the home side looking the most likely winners.
But Gouffran, a 62nd-minute replacement for Loic Remy, pounced in the 73rd minute to stab home the loose ball after Villa keeper Brad Guzan spilled an initial effort from Ben Arfa.
Steve Sidwell put Fulham ahead in the 22nd minute and the home side had three more efforts disallowed by Dimitar Berbatov - twice - and Hugo Rodallega before McAuley rose highest to head home Chris Brunt's corner.
Peter Whittingham converted a Ben Turner cross in the 59th-minute to earn a 1-1 draw for Cardiff at Hull, who had led through a 40th-minute header from Curtis Davies.
