Erling Haaland (2), Tijjani Reijnders and Rayan Cherki struck for the visitors in their Premier League opener.
Afterwards, Guardiola said: "(I’m pleased with the) result and the first half. The second half we were away from where we want to be but it’s normal for the first game.
“We trained a lot and just played two games - not much. But I liked many things and the second half Wolves were a bit better.
“We punished them on transitions because we have incredible pace with Oscar (Bobb), Tijjani and Erling (Haaland).
“It’s a weapon that we want to use this season to attack quicker than we did before but for the first game it’s always a little bit how will be the team. It is always a struggle here. I’m really pleased for that.”
New signings impressed
“The club always made good signings, I never found a player that is not good,” Guardiola said. “If you are playing in the Premier League it is because you are good.
“How you become better is how you connect with your teammates and the ideas. My job is to make the players connected but all of them are really good.
“(Rayan) Ait-Nouri knows the Premier League and Rayan (Cherki) is good but Tijji gives us something that we have missed with incredible pace to the box.
“The talent for Cherki is unbelievable in small spaces, the creativity is extraordinary and in certain games we will need him.”
