Manchester City mined their rich resources to break the resistance of a dogged Hull City on Saturday with 20-million-pound striker Alvaro Negredo coming off the bench to prove his worth in a nervy 2-0 Premier League win.
With memories of last weekend's defeat to another promoted outfit Cardiff City still fresh, City again looked edgy in defence and lacking attacking inspiration before Negredo found the net.
The Spaniard, who was brought on at halftime and later followed onto the pitch by more high-cost talent in Samir Nasri and James Milner, brought relief to the fans inside the Etihad Stadium with 25 minutes to play when he clinically headed home.
Yaya Toure added an undeserved gloss to the scoreline with a fantastic curling freekick from 20 metres in the 90th minute to give City six points from their opening three games, moving them up to second in the table.
West Ham United missed the chance to join Chelsea at the top of the table on seven points after a Jermaine Pennant freekick gave Stoke City a 1-0 win, while Norwich City beat Southampton 1-0 to record their first league victory of the season.
Newcastle United's Hatem Ben Arfa scored his team's first league goal of the season to give them a 1-0 win at home to Fulham, while Everton drew for the third straight game 0-0 at Cardiff City.
In the weekend's big matches, third placed Liverpool take on Manchester United at Anfield on Sunday while Tottenham Hotspur travel to Arsenal in the North London derby.
