MANCHESTER -- Sergio Aguero was delighted to reach the Champions League semifinals because it showed the progress Manchester City have made under manager Manuel Pellegrini.
Pellegrini will leave the Premier League club in the summer to be replaced by Bayern Munich boss Pep Guardiola.
But in his three years at the Etihad, City have improved their Champions League record -- after failing to get past the group stage in their first two seasons in the competition.
Now they have reached the last four for the first time in the club's history following their 3-2 aggregate victory over Paris Saint-Germain and Aguero believes they can go even further.
The Argentine striker told reporters: "The confidence is there, we are in the semis and anything can happen. We will be at our maximum, depending on who we play against but we will be going all out to win it.
"We know that [Pellegrini] won't be there for the next season so to be in the semis is something really amazing, it gives us great pride to take City to this level.
"We won well, at times we couldn't control the ball but we played pretty well, we knew how we had to play and I hope, we hope we can continue in the same fashion.
"This was our goal, to be among the four best teams in the Champions League and now we want to keep growing."
The only sour point on the night for Aguero was a first-half penalty miss that could have eased the tension on a nervy night at the Etihad.
It was his second miss from the spot in three attempts but the 27-year-old said he will not dwell on it.
He said: "These things happen, I'm not on a good run with penalties but the important thing is we qualified and I will get another chance to make up for it soon. "I have scored a lot of goals but the important thing is to get through.
"Obviously it's not nice to miss a penalty but I'm happy because the moment passed and the most important thing is at times we played very well, so we're pleased.
"Paris are a great team, they have very good players we knew that we did a great job over there, here at home with the fans support I think we did what we had to do."
Aguero's former club Atletico Madrid could join City in the semifinals of the Champions League if they can overcome a first-leg 2-1 defeat to Barcelona on Wednesday night.
But the striker believes they will face a difficult task whoever they are paired with in the last four in Friday's draw.
He added: "At this point you cannot choose [an opponent]. To win the Champions League you have to play against the best and today [Tuesday] we were up against one of those, a favourite. Now we'll have to see who the other candidates are but we know it will be tough.
"I obviously hope the best team goes through, Atleti in the last few years have improved a lot and I think they can give Barcelona a really tough game. I played in Atletico and I want them to do well."
