City won with goals from Mario Balotelli, Adam Johnson, Vincent Kompany and James Milner against his former club and moved on to 22 points from its eight matches, two points clear of United. The last time City topped the table at this stage of a top-flight season was 34 years ago.

Chelsea beat Everton 3-1 in an evening kickoff to move to within a point of United in third place, while Liverpool stayed fifth.

Fourth-placed Newcastle United play Tottenham Hotspur, who are sixth, on Sunday (1500 GMT).

City, without out-of-favor Carlos Tevez, the injured Sergio Aguero and with top scorer Edin Dzeko on the bench, was still far too strong for Villa, which suffered its first league defeat this season.

City manager Roberto Mancini told Sky Sports afterwards: "It's normal when you return after the international break that you have a problem at the start of the game, but after that we started to play very well." Balotelli put City ahead with an overhead kick after 28 minutes — his fourth goal in his last four games. Mancini said: "I hope Mario continues like this." City had the match won by the 52nd minute, when they were 3-0 up, before Stephen Warnock pulled one back for Villa only for Milner to score with a brilliantly worked goal he started and finished.

City has now scored 27 goals in its opening eight matches, having won seven times and drawn once. It faces United at Old Trafford next weekend.

In the lunchtime kickoff at Anfield, Steven Gerrard, making his first start for seven months, put Liverpool ahead with a 68th minute free kick against United before substitute Javier Hernandez equalized for the champions with an 81st minute header five minutes after coming on.

Chelsea stayed third when it saw off Everton at Stamford Bridge with first-half headers from Daniel Sturridge and John Terry and a third after 62 minutes from Ramires.

Everton, who had drawn with Chelsea on its last five league visits to the Bridge and knocked it out of the FA Cup there last season on penalties, was largely outclassed. Their only bright spot was when Apostolos Vellios scored in the 82nd minute, less than 20 seconds after coming on as a substitute.

Bolton Wanderers moved off the bottom of the table when they ended a run of six successive league defeats with a 3-1 win at fellow strugglers Wigan Athletic, where they could even afford to miss a penalty through Kevin Davies.

Blackburn Rovers picked up only its fifth point of the season with a 1-1 draw at Queens Park Rangers, who are still looking for their first home win, but the point was not enough to keep Blackburn off the bottom of the table.

Heidar Helguson put QPR ahead after 16 minutes before Christopher Samba headed Rovers level eight minutes later.

Norwich City maintained its good start with a 3-1 win over Swansea City in a battle of two of last season's promoted teams at Carrow Road, while Stoke City beat Fulham 2-0 at the Britannia with Jon Walters and Rory Delap scoring in the last 10 minutes.

Gerrard, returning for Liverpool after a complicated groin injury, struck with a free kick that went through the defensive wall after Rio Ferdinand had tripped Charlie Adam just outside the penalty area.

Hernandez, who came on as a 76th-minute substitute for Phil Jones, then nodded the ball into an empty net from point-blank range after Danny Welbeck had flicked on a corner.

"It wasn't the best free kick," Gerrard told Sky Sports. "I tried to get it over the wall but I got a bit of luck.

"To come back and play my first full 90 minutes today ... growing up these are the games you dream of playing in and when you are sitting in the stands there is nothing worse. To be out there experiencing the emotions again was fantastic."

United defender Ferdinand, who has also had a spell out injured, said: "It was great to be back and after losing here for the last three visits I'm pleased we've left with a point." The visitors started without Wayne Rooney, Hernandez or Nani up front although all came on in the second half.

Liverpool, buoyed by the return of Gerrard, who had made three previous substitute appearances this season, had more possession and looked more dangerous as the match wore on and went close to a winner several times in the final minutes.

Rooney, who was handed a three-match ban for Euro 2012 by UEFA on Thursday following his England sending-off against Montenegro last week, came on for the last 20 minutes but made little impact, and United manager Alex Ferguson revealed why he left him on the bench afterwards.

"Wayne has had a bad week," Ferguson told Sky Sports. "He's devastated with the suspension. I must say that.

"When you think about it he could quite feasibly miss the European Championship because it's never certain you'll qualify from a group.

"It's been a bad week for him, really. I felt with these circumstances that he's better off starting from the bench."
