City produced a night to remember in the Portuguese capital, recording our biggest ever away win in the Champions League.
In the process we also became the first team to record five consecutive Champions League knockout away wins.
But reflecting on the victory, the City boss insisted there were reasons for improvement. And he claimed there were still areas for the side to work on as the business end of the season looms into view.
“Don’t misunderstand me. I am more than delighted,” the boss declared.
“I know how difficult this competition is. 5-0 is fantastic, today we were so clinical, arrive goal, arrive goal, arrive goal and when that happens it is difficult for the opponent.
“But we didn’t do our build up well.
"We defended well and we got an incredible result.
“But we have a duty as a manager and as a team to analyse exactly how we performed individually and collectively. Not just the result.
“The result is a dream but we can perform better.
"Not just in the Champions League, but in the Premier League we always concede few. We concede so few shots on target in every game. This is important.
“We have to take care of the few chances they had. But I say the same, we are not a team that defend well.
“If you analyse individually we are not defenders, we are an offensive team in most departments. We have to do it with the ball.
"We have to take better care of it than we did today.
“Today it was because we were so clinical. We arrived and scored and when that happens it is mentally difficult for the opponent, you get confidence and you relax.
“Sometimes football is margins. Sometimes you win games for this and all the analysis is how good one team is, how bad the other one is but it is the margin.
“Maybe you have this duty and you have another one is to see how they perform individually and the team and the plan depends on how they play if we execute it as well or not.
“Don’t misunderstand me, it is a dream, a perfect result and so good for the second leg. But we can do better."
