The champions opened their campaign with the same scoreline at home to West Brom last weekend, although they were made to sweat at the DW Stadium before running away with the game late on.

Florent Malouda scored the only goal of a tight first half before a Nicolas Anelka double early in the second period opened the floodgates for substitutes Salomon Kalou (two) and Yossi Benayoun to seal an emphatic success.

"We have started well this season, scoring a lot of goals, playing good football," Ancelotti said.

"But the first half was tough. Wigan played good football, put pressure on us, and we were not able to play our football as there was no space.

"But is impossible to think we have to score six goals in a game all the time because this is not real football, this is PlayStation football."

Arsenal also struck six without reply as they brought newly-promoted Blackpool back down to earth with a thud following their 4-0 opening-day win at Wigan.

Theo Walcott scored a hat-trick with further goals from Andrey Arshavin, Abou Diaby and summer signing Marouane Chamakh punishing Blackpool after Ian Evatt's first-half dismissal.

Arsenal boss Arsene Wenger praised Walcott afterwards, saying: "Theo is more electric than he has been.

"He mixed well the final ball and the finishing, which is a sign a player is more mature."

Seasiders boss Ian Holloway was just happy not to lose by more.

"It was an absolute education, a masterclass - but we have to learn quickly," he said.

Gareth Bale's double gave Tottenham a controversial 2-1 win at Stoke.

New Potters signing Jon Walters looked to have scored a late equaliser only for referee Chris Foy to rule it had not crossed the line after Peter Crouch's block.

"Sometimes they go for you, sometimes they don't. I don't think any referee goes out there to make a bad decision now. You have to take it on the chin," Stoke boss Tony Pulis said.

New West Ham boss Avram Grant insisted he was "very happy" despite his side's 3-1 defeat at home to Bolton.

Carlton Cole missed an early penalty before a Matthew Upson own goal and Johan Elmander's double sealed Bolton's first win.

The Hammers, beaten 3-0 at Aston Villa last week, now head into fixtures against Manchester United and Chelsea rooted in the bottom three without a single point.

Grant said: "We have a very tough two games. If you saw the spirit today after the game last week, this team this season is not going to give up."

Craig Gardner scored twice and Ben Foster saved a penalty as Birmingham beat Blackburn 2-1 while new West Brom signing Peter Odemwingie scored the only goal in his side's 1-0 home win over Sunderland.

Sylvan Ebanks-Blake's 74th-minute equaliser ensured Wolves stayed unbeaten as they drew 1-1 at Everton, who had gone ahead through Australia international Tim Cahill.
