The Spaniard was happy with the win, but still wants more from his players, including Aguero, who has now scored 11 times in six games so far this season.

“I want to congratulate him on his performance, especially for the first goal,” Guardiola said. “I am so happy for him. But I think he can play better and I will try to tell him.

“He has great ability and in the box, there is nothing I can do to help him. But maybe I can help him develop, like keeping the ball and helping the rest of the team.”

Swansea, beaten by Guardiola’s men in the League Cup in midweek, certainly gave City a tougher test than their lowly league position suggested was possible.

“I was not surprised by Swansea. It is not easy to play twice a week with the same team, so both teams changed,” Guardiola added.

“But they have good players and the goal they scored was very good. But I thought we did well with the ball.

“We were able to attack behind the midfield line and that was what I wanted. We played really well in the second half and we created some good chances. I think we deserved to win.

“It was an important win and now we have two games before the break.”

The only setback for City was the sight of Kevin De Bruyne limping off in the second half.

“Kevin is injured, I think. It is a pity. From the way he reacted, it looked like a muscle injury,” Guardiola said.

“We will have to wait and see when we get back to Manchester, He will be going in to see the doctor on Sunday.”

The pressure is certainly mounting on Swansea boss Francesco Guidolin, for whom this was a fourth league defeat of the season.

“The performance was good in my opinion. Manchester City is the best team in the Premier League, but I thought my team played at the same level as them,” Guidolin said.

“I am proud of my players, but of course, I am disappointed with the result. Before the penalty we had a good chance to score and I thought we deserved to score.

“It had been a good game for us up until then. But then we conceded and we lost the game. However, if we play this way in the future, we will be okay.”

On the penalty, awarded by referee Neil Swarbrick at a crucial time of the game, Guidolin said: “I am not one to judge the referee. The referee is the judge. My opinion is not important.

“I said thanks to the referee after the game because that is the attitude I have towards referees.”

But it certainly doesn’t get any easier for Swansea as they play Liverpool next weekend and then Arsenal on October 15 at the Emirates.

“Our fixtures are not easy in this period and in terms of our results, we are not in a very good moment,” Guidolin added.

“But our performance on Wednesday and today has been great. I don’t know what the chairman or the owner think. But that is not important. What is important for me, is that I work hard with the players and have a good relationship with them.”
