Chelsea edge out Norwich, Wolves draw

Juan Mata scored on his debut for a still-stuttering Chelsea in a 3-1 home win over promoted Norwich City as the Londoners joined Wolverhampton Wanderers at the top of the Premier League on Saturday. Andre-Villas Boas's new side have failed to sparkle in the early weeks of the Premier League season but Portuguese full back Jose Bosingwa gave Chelsea a superb early start with a rare goal from 22 metres.
--- Blackburn miss two spotkicks in Everton win
--- Drogba recovering after being knocked unconscious
Chelsea striker Didier Drogba was knocked unconscious during Saturday's 3-1 win over NorwiCh City but is showing "progressive signs of recovery", coach Andre Villas-Boas said. The Ivorian was drafted back into the starting lineup to partner Fernando Torres up front but was accidentally punched as Norwich goalkeeper John Ruddy came out to meet the ball.
Droga was already unconscious from the punch and hit the ground awkwardly. He did not move initially as medics attended to him but he then started to flex his arms before being stretched off. The game ended up having 11 minutes of stoppage time. "He will have a full exam. He was completely unconscious," the Portuguese coach said.
Wolves had won their opening two fixtures, like Manchester City and Manchester United, but were content to leave Aston Villa with a 0-0 draw after the Birmingham-based side put their local rivals under the cosh for long spells. Argentine Franco Di Santo scored twice to give Wigan Athletic a 2-0 home win over promoted Queen's Park Rangers with the visitors deciding not to give Joey Barton a debut after his move from Newcastle United.
Villa and Wigan are joint fifth. Hapless Blackburn Rovers lost 1-0 at home to Everton after Junior Hoilett and Mauro Formica both missed penalties for the home side before Mikel Arteta made no mistake with his injury-time spotkick. Promoted Swansea City, still looking for their first Premier League goal, drew 0-0 at home to Sunderland in a game where both sides hit the bar.
