Reigning champions Manchester City celebrated manager Roberto Mancini’s 100th Premier League match in charge with a 3-1 victory at home to Queens Park Rangers on Saturday.
Yaya Toure gave City a 16th minute lead at Eastlands when he scored from close range following a corner.
But Italian boss Mancini would have been fuming when QPR, managed by his City predecessor Mark Hughes, equalised against the run of play in the 59th minute.
England goalkeeper Joe Hart could only parry a fierce drive from Andy Johnson and Bobby Zamora headed into an empty net.
But parity lasted just two minutes with Edin Dzeko heading in an excellent Carlos Tevez cross.
Argentina striker Tevez put the result beyond doubt in stoppage time when he deflected in Dzeko’s wayward shot.
Earlier, Andre Villas-Boas was still left searching for his first win as Tottenham Hotspur manager after a 1-1 draw at home to Norwich.
The Portuguese boss, after several fine saves by Spurs keeper Brad Friedel kept the game goalless, saw his side take the lead when Mousa Dembele, signed from Fulham this week, scored on his club debut in the 68th minute.
But, as happened in their draw with West Brom, Spurs conceded a late equaliser when Robert Snodgrass scored five minutes from time at White Hart Lane.
The result will only increase the pressure on Villas-Boas, sacked by Chelsea last season before Spurs’ London rivals won the Champions League, to prove he can succeed in England.
“We are very disappointed with the way we have played,” Villas-Boas told the BBC.
“The players are down, we lacked the sharpness we needed and perhaps allowed some anxiety to creep into our game.
“I understand why the fans are frustrated. No one wants to draw two games at home like that but we will repay their faith.”
Swansea missed the chance to go top of the Premier League after a 2-2 draw at home to Sunderland.
West Brom’s impressive start to the season continued with a 2-0 win over fellow high-flyers Everton.
Shane Long gave the Baggies a 65th-minute lead before Gareth McAuley sealed victory eight minutes from time.
Andy Carroll made an immediate impact at West Ham as the Liverpool reject inspired his new club to a 3-0 win over Fulham at Upton Park, setting up goals for Kevin Nolan and Matt Taylor either side of Winston Reid’s effort.
But the England striker’s debut was marred by a hamstring injury Hammers boss Sam Allardyce reckoned would rule him out of next week’s World Cup qualifier away to Moldova.
Wigan and Stoke shared the points in a 2-2 draw.
Stoke though made it 2-2 though Peter Crouch’s header 14 minutes from time.
