Though still only 25, his professional career is already ten years old, with his debut for boyhood club Independiente coming at the ludicrously young age of 15.
It made him the youngest player ever to debut in Argentinas top-flight, breaking a record held by Diego Maradona, and was the first in a series of career benchmarks that include an Olympic gold medal, Atletico Madrids first major European trophy since 1962 and most recently a strike that won Manchester City their first league title in 44 years.
When Sport meets him, Agueros role in Manchester Citys 4-0 victory over Newcastle is less than 24 hours old, but he is already back on the pitch and playing his part in another match.
Two young City fans (and one more sheepish observer sporting a Barcelona top) have been waiting patiently to catch a glimpse of one of footballs elite, and eventually their wish and a whole lot more besides is granted.
The Argentinian sets up a game of two against two: himself and one kid against the Barcelona boy, who he calls Messi, and his friend. Only after the kickabout reaches its conclusion is he prepared to begin our interview.
This is a man who evidently still loves football for footballs sake. He is equally enthusiastic about his new boss, Manuel Pellegrini a man who reportedly allows his players more room to improvise on the pitch than other managers. So, is that true?
Yes, he speaks with every one of the players to see how they like to play, says Aguero. In my case, he wants me to play with freedom and to be calm on the pitch, so that I can get in on goal. But also so that I enjoy myself.
After working with him for a little while, has Aguero noticed anything else particularly distinctive about Pellegrinis methods?
Every coach has his way of doing things his tactics, he reveals. Were very happy with the new arrival and now we just have to try and adapt to the new ideas that he wants to put in place. Against Newcastle, we not only played very well, but carried out his tactics and the way he wants to play.
We suggest it must be nice to see the new boss favouring a system with two strikers, especially after Aguero had such success in tandem with Diego Forlan (also a former Independiente player) at Atletico.
Yes, I really like playing with other strikers, he agrees. It means there are more players getting in on goal regularly and getting involved thats why I like it. Since I started out, Ive always played with another striker. At Independiente I played with one other. At Atletico with another, with Argentina I play with two strikers... or, rather, three in total. And here, with two. Its much better because there are more opportunities to attack and try and score goals. That said, its the coach who will decide how he structures his line-up to make sure we play the way he wants us to.
That use of two strikers is a key facet of Pellegrinis preferred 4-2-2-2 a system he used effectively at Villarreal, Real Madrid and Malaga, and one he has now brought to the blue half of Manchester. Though not commonly used in Europe, it is a particularly South American system surely something that suits Ageuro?
Its easy to adapt to because he has a South American style, he confirms. He hasnt changed his style since he was at Villarreal, or Malaga, and hes conveying it here. Hes happy with the way its working; we have the ball more, and we move the ball towards the goal much quicker.
Its still very early in the season, and not everything went to plan in last Sundays 3-1 reversal in Cardiff but, based on Citys display against Newcastle, that South American style is going down well at the Etihad. As are the arrivals of Jesús Navas and Fernandinho. Their introduction, coupled with the new-found competitiveness they bring to the squad will, Aguero believes, help City challenge on all fronts this season.
I think we reinforced well, he says. They will certainly give a lot to the club. I think there is a really good level here in order to compete for the Premier League, the Champions League and the other cups. I hope we continue in the way we started, and well see at the end of the year how everything goes...
The Champions League may not hold good memories for City, but their new manager is something of a specialist in the competition. When we ask Aguero if progress beyond the knockout stages, at the very least, is a key goal for City this year, he is quick to give us a definite answer:
Yes. The first goal is to progress, yes. Get to the knockout stage. Afterwards? Well have to look at who we cross paths with, and then try and do everything possible to get as far as we can. The most important thing is to perform well in the group stage to get to the last 16.
Since Agueros arrival at City two years ago, a wave of players from La Liga have followed the same path to England. Could this influx of players who honed their trade on the Iberian peninsula have an impact on the style of football played in the Premier League?
I dont know, he speculates. Theyll always play the same in the Premier League. But as more players from La Liga come, the Premier League is getting better technically, and thats good for the English game. Its nice that there are quality players coming, because it draws attention from across the world.
And what of the league he has left behind? The exodus of stars from La Liga to England is seen by many as a consequence of the unfair distribution of TV money in Spain, with Barcelona and Real Madrid able to negotiate their own deals individually and earn much more than their competitors. Does that, we wonder, damage La Liga, preventing it from being as competitive as it should be?
Thats exactly what its like, Aguero agrees. It damages the league. Only Barca and Madrid can strengthen with top-level players, and the others cant reinforce well. The logical thing would be if it was more like here in the Premier League that the money was shared to everyone more equally, and that every team could strengthen in order to try and stay in the league, or win titles. It makes the league better, too. These are problems for the Spanish league to deal with, but evidently it favours Barca and Madrid, rather than the other teams. Thats clear.
That said, Atletico Madrid have enjoyed themselves since Agueros departure, winning a second Europa League in three seasons by trumping Athletic Bilbao 3-0 in the 2012 final. They followed that with a Copa del Rey victory in the Bernabeu in May, beating city rivals Real 2-1 in extra-time, with Agueros compatriot Diego Simeone overseeing it all.
Hes doing a good job, and obviously Im happy because hes Argentinian and things are going well, says Aguero. Hes getting the chance to become well known in Europe and across the world, so Im pleased its going well for him, and for the club.
With Tata Martino, Barcelonas new boss, also hailing from Argentina, and Marcelo Bielsa taking Athletic Bilbao to two cup finals in the 2011-12 campaign (losing the Copa del Rey final to Barca), Argentinian managers are, we suggest, particularly sought after in Europe.
There are good, bad and average Argentinian coaches, like coaches from any country, says Aguero. But the good ones are in Europe, and thats great for Argentina, our people and for our football too. So Im happy.
Argentina are currently top of the CONMEBOL qualifying table for the 2014 World Cup, and look stronger than they have in years. Can they be considered one of the favourites to lift the trophy in Brazil?
Aguero doesnt think so: No... favourites? No. I think that we have a great team, though. I really hope we have a good World Cup, and getting as far as possible is the most important thing. If we can bring it home, even better. But there are other countries that are even more difficult to beat waiting ahead, so its all left to play for. World Cups arent easy, it all comes down to what happens there in that moment. We have to prepare well, be in good shape, and mentally believe that we are capable of winning it. But its very difficult.
Would lifting the trophy on Brazilian soil be particularly sweet for an Argentinian?
First and foremost it would be important for an Argentina team to win the World Cup in any place for the players, for the country, he says. It happens only once in a lifetime, so obviously winning a World Cup would make any Argentinian player extremely happy. And, moreover, the people.
Playing for his country also presents Aguero with a rare opportunity to play alongside Lionel Messi. Could that be a possibility at club level, one day?
Yes, he should come to Man City, he says with a smile. Then well definitely play together! City should buy him!
And with that, Aguero takes his leave, probably in search of another impromptu game of football. The kid from Quilmes is quite clearly all about the game. And if things go well this year for City and Argentina, the game itself could end up being all about him
