Guardiola feels the scoreline could have further advantaged his side as they were at times at their absolute best throughout the contest which saw them join neighbours Manchester United and Chelsea on nine points at the top of the table.
"Here we have to win 2-0, 3-0, 4-0 to think that the game is over because they play long balls behind our full-backs," he told Sky Sports 1.
"They win the second balls, they are taller than us. They jump more than us but we played a real good game. I think our defence enjoyed it and we are happy with what happened in this match.
"The only way they scored a goal was to cross the ball and when that happens they are so dangerous. They are taller in the box so they play in that style and that can happen. Then it was 2-1 and the emotion, the tactics they are in.
"We created many, many chances. I don't know how many chances we create and how many shots on the goal. The performance was really, really good with the ball and without the ball. With the quality of our players we can be satisfied.
"In Bucharest (in the Champions League qualifier) we played amazing.
"In the Premier League it's complicated - against Sunderland we played good for just minutes and Stoke City we adapted really really well in the conditions and here we played maybe the best minutes in the Premier League."
