Manchester City midfielder David Silva says last month's thrashing of Manchester United proves his side are ready to claim the Barclays Premier League title.
The Spaniard has spearheaded City's rise to the top of the table this season, scoring three times and making six assists amid some sparkling displays.
City's thumping win at Old Trafford extended their lead over United to five points, a gap that Silva believes will be too much for the 19-time league champions.
"Five points dealt United a blow to their morale and made it hard for them," he said. "Our win over them showed we are the team to beat in England. We have shown we can become champions.
"In the summer, Mancini promised us a bigger attacking system and is fulfilling what he said. I think we are creating many openings because of this strategy."
As well as Silva's mesmeric form, another blueprint of City's unbeaten start to the Barclays Premier League has been their ruthlessness in-front of goal.
With 36 goals in the league already this season, only Preston North End, in the first season of the Football League in 1888/89, have scored more goals in their opening 10 league matches.
On their way to finishing third last season, Roberto Mancini's philosophy relied on snatching narrow single goal victories, while matches against their rivals turned into tight, tense affairs.
This season has seen a change of emphasis from the Italian boss, leading to a deluge of goals and Silva is revelling in the side's new found freedom.
"I am enjoying my best form ever - including my time with Valencia," he added.
"I am the same person as last season but, as a footballer, I have matured a lot. I know the City style better and have adapted to all aspects of club life.
"My English is more fluent and this always helps in communicating with my team-mates. In my early days here, I suffered a lot of anxiety over this.
"Roberto Mancini insists I improve my performances even more and that's my challenge. I am a winner. I dream of winning the Premier League."
