Chelsea kept their place at the top of Premier League table after a 1-0 victory over Wigan at the JJB Stadium.
The Blues has six points after two matches and leads Liverpool on goal difference.
Deco, who scored on his Premier League debut last weekend, registered his second league goals with a superb free-kick after just four minutes.
Wigan new signing Lee Cattermole was adjudged to have handled the ball outside the box, and the Portugal star stepped up to fire past Mike Pollit, who was called into the side for the injured Chris Kirkland.
In the City of Manchester Stadium, Manchester City dumped 10-man West Ham 3-0 with a double from Elano and one from Daniel Sturridge to give new manager Mark Hughes a first league win as Manchester City boss.
Midfielder Mark Noble was shown the red card after 38 minutes after getting two yellow cards and made him the first Premier League player sent off this season.
City took the advantage and the goals came from Sturridge in the 65th minute with a further two from Elano.
The second half lasted almost 55 minutes because of an incident when City's defender Micah Richards clashed heads with team mate Tal Ben Haim shortly after the break and was taken to hospital as a precautionary measure.
