Minutes later, the 27-year-old rounded up the Citizens' emphatic win at the Cardiff City Stadium with a brace after goals from Sergio Aguero, Bernardo Silva and Ikay Gundogan had given the visitors a three-goal lead in the first half.
However, Guardiola, pleased with the winger's display, is positive that the 2016 PFA Player of the Year will play a crucial role as his team aims to retain the league title.
“He played well. He’s a guy who’s going to help us a lot," Guardiola told the club website.
"He is a special talent and in front of the goal he has incredible quality.
“We are so satisfied with him. We won 5-0 in Cardiff, conceded few chances, so, yeah, very pleased.”
“The level today was the level of last season. Were a little bit under par in the first half on Wednesday, but we must not forget Champions League opponents are good, too,” he added.
“We knew, it’s part of the process. The season is long, there are a lot of games to play and it’s important after one bad result that the team came back to where it normally is.
“To score goals you have to be patient. We were patient, we didn’t suffer in the long balls and free-kicks and that’s important.”
