The Bosnian international found the net in City’s 3-0 over Blackburn on Saturday, notching his 18th goal of the season.
However, his Argentine team-mate this week returned to training after apologising over a four-month long bust-up with manager Roberto Mancini.
But Dzeko believes that Tevez's comeback and more high-scoring wins can only help the Citizens as they remain in the hunt for the Premier League title.
He said: "It's not pressure, it's just that he can bring quality to the team. We are all one team trying to play together and it's good that we scored three because in the end goal difference could be the key.
"That is normal but it's good you have so many quality players around you, and that they are all getting better."
Dzeko had to settle for a place on the bench against Rovers, with Roberto Mancini favouring Mario Balotelli, but the Bosnian insists he won't complain over the manager’s decisions.
He said: "Of course [it is frustrating], when you have scored so many goals. OK, sometimes you can play badly, but in the end it's the decision of the manager and I respect that.
"We won 3-0 so no-one has to say anything. My goals are talking for me, so I'm happy."
The 25-year-old is also confident City can go on to lift the Premier League title but says they have to be at their best as rivals Manchester United will provide fierce competition.
He said: "When you see the players like Aguero, (David) Silva and Yaya (Toure) and the others, you think, 'Wow, we have to win this' and with these players we can do it, because they are amazing.
"It's still 12 games and we have to try to win every one, then we are surely on top. It won't be easy because United are just behind us, but we will see."
