Dzeko feels at full strength
Dzeko scored four times as he and debutant Samir Nasri helped put Spurs to the sword with a ruthless display of attacking football. Nasri supplied the crosses for Dzeko to score his first two goals and he also played his part in the run up to Sergio Aguero's strike, which made it 4-0 with half an hour to go.
Younes Kaboul headed home a consolation goal for Tottenham, but the afternoon belonged to Dzeko, who clinched his hat-trick with the last kick of the match.
"I think the last time I scored four was for Wolfsburg in Germany," he told ESPN. "Today was something special for me - to score four goals in the Premier League is fantastic.
"I think we're getting better and better. I hope we can improve in the next game and try to win every game."
Nasri added: "This is a tough place to win. I had a good game but the most important thing is we won 5-1 and sent out a signal to other clubs. This is just start of the season, it's important to keep our confidence, but I'm convinced we have a great team here and can win things."
City manager Roberto Mancini admits today's rout will have raised expectations amongst the fans, but was quick to remind them the season has only just begun.
"We played a really good game against what is a fantastic team," he said. "I was always sure Dzeko would score a lot of goals for us, he always scored in Wolfsburg.
"The only thing I'm disappointed with is that we conceded. I think we need to pay more attention in this situation. This is a very long season and it's important that we started well. The next games will be very hard because now everyone thinks we will score three or four goals, but that is impossible."
