The Citizens continued to blow the competition away as Saturday’s 2-0 win over Leicester City made it 10 straight Premier League wins and 12 without defeat to sit eight points clear at the summit.
Next up for City is the UEFA Champions League visit of Feyenoord on Tuesday where Guardiola’s men will be looking to maintain their 100 percent start in Group F.
De Bruyne said: "[Guardiola has given us] the confidence that we can beat everybody.
"Last year, there were games where we could have been better but we weren't clinical enough.
"This year, even today, we could be more clinical. But we were there in the box, we are scoring more goals and I think that's the main difference from last year.
"It's not about me. It's about how the team plays and the way that the team is playing makes it easier for me.
"Obviously I think it is a type of football that is good for me as a player individually.
"But I think also the way that the team is playing, it just makes it easier for everybody."
