"Rottweiler! If you score a goal, I'll buy you a barbecue beef sandwich."
That was Sergio Aguero's father Leo egging his son on when he was just a kid trying to make it to the big leagues like any other footballer. Of course, Aguero then took the ball from his own goal, dribbled past the entire opposition, and scored. He made sure his father kept his promise.
'Kun' Aguero was so good as a teenager that he when he played with the neighbourhood kids, they would stick him in goal. That's where he played on Sundays. On Saturdays, he would be taking to the field for the senior team of Club Atlético Independiente.
Yes, a 15-year-old Aguero actually played for the first team. In the process, he broke the record for the youngest player to make his debut in the Argentine Primera División - a record previously held by a certain Argentine legend by the name Diego Maradona.
Ever since his debut, it has been a long journey for the striker. From Argentina to Spain to England, from Independiente to Atletico Madrid to Manchester City to the Argentina national team - he has scored more than 350 goals in his career. He's still only 29.
Everyone remembers Martin Tyler screaming "Agueroooo" into the mic when he scored arguably the most historic goal in the Premier League era to give City the title in stoppage time of the final game of the season.
But commentators were already doing that when he was making a name for himself back home in Argentina.
Making a name for himself in Argentina
Like many footballers from South America who struck gold in Europe, Aguero came from a humble background. This documentary traces his life from the time he lived with his family in a simple house and the unconditional love that he received from his parents.
Of course, that's not all. They discover the mud pitches where Aguero perfected his skills as a young kid, learning from the older ones and then taking them on without fear. Testimonials from his former coaches only serve to enlighten us about how good Aguero was as a kid.
Those hard neighbourhood pitches were where he spent most of his time and even his compatriot and teammate Lionel Messi explains how they help perfect one's skills before they switch to grass.
Word spreads quickly when it comes to young footballers with talent and that is how Independiente got involved. He was good enough to be fast-tracked to make his debut for the first team - also a very emotional moment for his mother who was watching her son play in a stadium for the first time.
"He's at his peak when he is inside the box. He doesn't forgive you, he's a killer." - Former Argentina manager César Luis Menotti
Despite his sudden rise to fame, the documentary also shines a light on his humility and his quest to better himself. Aguero never let fame or money interfere with his love for the game.
There is also a lot of focus on Aguero's relationship with Messi. Two players who won the U-20 World Cup together and have been inseparable ever since - be it through success on the pitch or hardships off it.
The importance of Aguero's rise to stardom as a 15-year-old is also depicted by the fact that he won the U-20 World Cup not once but twice. How many players have that claim to fame?
The move to Europe and glory with Manchester City
Aguero was still a teenager when Atletico Madrid came calling and the striker explains his reservations about a move to a club halfway around the world when he was just taking his first steps in Argentine football.
However, when a club receives a record bid especially for a player so young, it is hard to ignore. The rest, as they say, is history.
Aguero would score 101 goals for the Rojiblancos - a club known for churning out strikers at a regular rate. He would even across an old friend who was now a rival in La Liga - a young forward at Barcelona - Messi.
Aguero would win the Europa League and the Super Cup before the next step in his journey. The move to Manchester City. At the time it was a record-breaking move. In hindsight, it was probably the best £38m a Premier League club ever spent.
Fending off both Juventus and Real Madrid, Aguero signed on the dotted line for the Sky Blues and delivered in his very first season.
Right from his debut to the last kick of the season, he was La Maquina de Hacer Goles. The Goalscoring Machine. The man who eventually broke the club record for most goals scored.
"Inside the box he is one of a kind." - Lionel Messi
Aguero's heroics on the pitch are legendary. But this documentary helps us understand how he achieved such greatness - be it as a kid or as an adult. It helps us understand his psyche, his emotions, and his frame of mind when he ties his shoelaces and steps on the pitch.
And it is a must-watch for any football fan who has smiled when they watch Kun ply his trade for 90 minutes every week.
