Sergio 'Kun' Aguero is an Argentine forward who will join Barcelona once his Manchester City contract expires in June 2021. With 260 goals for City, he is the club's all-time leading goalscorer in all competitions and tops the club's scoring charts for the Premier League, continental and domestic cup competitions.

He is regarded as one of the greatest strikers in Premier League history and is particularly remembered for his title-winning goal against Queens Park Rangers in the 94th minute, which saw City win the Premier League on the final day of the 2011/12 season.

That trophy was the first of many which Aguero has lifted during his time at the Etihad, having won the title another four times, as well as winning six EFL Cups and an FA Cup.

The Argentine also had success on the European stage with Atletico Madrid, winning the Europa League in 2010 prior to his move to England. On the international front, Aguero inspired Argentina to Olympic gold at the 2008 Beijing Games, scoring a brace against Brazil in the semi-finals before overcoming Nigeria in the final.

Aguero has been selected for several major tournaments but is yet to taste glory alongside Lionel Messi, finishing runner-up in the FIFA 2014 World Cup and the Copa America on two occasions.

On March 29, 2021, he announced he would be leaving Manchester City after 10 years at the club. He later joined Spanish giants Barcelona on a free transfer. 

Aguero impressed in the early days of his professional football career after becoming the youngest player to feature in the Argentine Primera Division with Independiente at the age of 15 years and 35 days.

That record was previously held by World Cup winner Diego Maradona, who would go on to become his father-in-law. Atletico Madrid decided to pursue the young, exciting teenager and they broke their transfer record to get him to Spain in 2006, signing him for around $24million.

After the departure of Fernando Torres to Liverpool, Aguero quickly became a crucial part of Los Rojiblancos, especially in his second campaign when he scored 19 goals to help his side achieve their highest league finish in 12 years.

Atletico finished fourth in La Liga for the first time in a decade. Aguero won the Golden Boy award in 2007 - an accolade given to the most impressive young prospect in world soccer.

Two seasons later, he assisted two goals in the 2010 Europa League final against Fulham to earn Atleti their first trophy in 14 years and the first of Aguero's career. That victory qualified them to feature in the UEFA Super Cup, which they also won, in 2011.

Aguero continued to find the back of the net throughout his time at the Vicente Calderon Stadium, finishing with a goal tally of 100 goals in 230 games.

Despite previously stating his intent to stay, following the 2010/11 campaign he posted an article on his official website titled "Time to Leave" and it was not too long before Manchester City clinched his signature. Atleti fans were furious with the nature of his departure, displaying flags with the words "Aguero, We Hope You Die."

After consistently scoring during his five seasons at Atletico Madrid, Manchester City paid a reported $46million for Aguero in July 2011. The forward arrived with big expectations having scored 20 La Liga goals in 2010/11, and the Argentine did not disappoint on his debut for City.

Kun netted twice and claimed an assist in just a 30-minute appearance off the bench against Swansea City in the Premier League, which was a sign of things to come.

Aguero went on to score 30 goals in all competitions in his maiden season, but none were as important as his last of the campaign. City found themselves needing a victory against Queens Park Rangers on the final day to clinch the Premier League title and they did so in the most dramatic circumstances.

Requiring a goal to pip fierce rivals Man United, Aguero fired home a winner in the 94th minute to give City a 3-2 victory over QPR. The goal, which will forever be one of the most famous in the history of English football, meant that his side were top flight champions for the first time since 1968.

Since then, Aguero has continued to engrave his name into City history by setting a number of club records. Those include having netted the most hat-tricks in all competitions with 16 and the most goals scored in a Premier League season - 26 in 2014/15.

He has twice been named the club's Player of the Year and has also been part of the PFA Team of the Year on two occasions.

Despite numerous long-term injuries, Aguero scored 260 goals in 390 appearances, making him the club's all-time top goalscorer. He won 15 trophies at the Etihad Stadium, making him the most decorated City player in history. He narrowly missed out on a 16th in his last game for the club, coming off the bench in City's 1-0 Champions League final defeat to Chelsea on May 29, 2021.

Aguero's contract at Man City expires in the summer of 2021 and the player announced on March 29 that he would be leaving the club.

“A huge sense of satisfaction and pride remains in me for having played with Manchester City for a whole 10 seasons - unusual for a professional player in this day and age,” Aguero wrote on social media.

He went on to say: "I will continue to give it my utmost for the rest of the season to win more titles and bring more joy to the fans.

“Then, a new stage with new challenges will begin and I am fully ready to face them with the same passion and professionalism that I have always dedicated to continue competing at the highest level.”

In the summer of 2021, Barcelona officially confirmed the signing of Aguero and he was unveiled at the Nou Camp in full kit.

He signed a two-year deal with a buy-out of €100million.

Speaking on his move to Barcelona, Aguero said: "We all know that Barcelona are the best club in the world.

"I think I made a great decision to be here and of course it is a step forward in my career.

"I am really happy and hopefully I can help the team to win things."

Aguero started his youth international career with a bang, playing alongside the likes of Messi, and Kun twice won the U-20 World Cup. At one of those tournaments in the Netherlands, he roomed with Messi and it was there that they formed a strong friendship which remains to this day. Indeed, this is one of the reasons why Aguero moved from City to Barcelona.

Aguero earned his first call-up to the senior Argentina squad in 2006 and made his debut at the Emirates Stadium in a friendly against Brazil. He scored twice against the same opposition two years later in the semi-final of the Beijing Olympics and went on to win gold with his country.

He made his first World Cup appearance in 2010 as Argentina made it to the quarter-finals, before then helping his nation reach the final four years later in Brazil.

Aguero scored a penalty in a semi-final shootout against the Netherlands and started in the final. However, he was unable to make a significant impact, with Germany defeating Argentina 1-0. He was on the scoresheet twice at the next tournament in France, including their 4-3 defeat to eventual champions France in the Round-of-16.

Aguero has a better scoring ratio in the Copa America format - a South American knockout tournament - having scored nine goals in his four tournaments. Argentina finished as runners-up two years on the trot in 2015 and 2016, before taking third place at the last tournament in 2019.

He finally got his hands on some silverware for Argentina at the 2021 Copa America.

Although his involvement was limited compared to previous tournaments, Aguero was part of the Argentina squad that won their first Copa crown since 1993 with them beating Brazil 1-0 in the final.

Aguero was previously married to Gianinna Maradona, the youngest daughter of soccer legend Diego Maradona. The pair were together for four years before their split in 2012 and have a son, Benjamin, who was born in 2009.

After their break-up, World Cup winner Maradona said: "He's a wimp who I don't even want to name. In my daughter's next meeting with a lawyer, I want to be by her side. We'll see who can talk. The next time I want to be there to see if he (Aguero) says anything."

As well as having Maradona as a grandfather, Aguero's son, Benjamin, boasts Lionel Messi as his godfather.

He is currently dating model Sofia Calzetti. The two spent the coronavirus lockdown together with their French bulldog, Capri and their other dog named Ella.

Aguero's mother, Adriana, was a housewife and his father, Leonel del Castillo, was a taxi driver. They were both teenagers when he was born in 1988. That led to some complications with authorities and so he took his mother's surname.

He has six siblings: Yesica, Gabriela, Maira, Daiana, Mauritius and Gaston. His nickname "Kun" was given to him by his grandparents due to similarities with a Japanese cartoon character called "Kum-Kum" who liked to cause trouble.

Sergio Aguero has a net worth of around $80million. According to Forbes, Aguero was the 84th highest-paid athlete in the world in 2018, earning $22.6million.

He has since dropped out of their top 100. Aguero earns around $17.1million in salary and earnings, on top of the $5.5million he receives from endorsements. He is sponsored by PepsiCo and Puma.

The new deal which he signed in 2018 at Manchester City is believed to have been worth around $370,000 per week, making him their second-highest paid player behind Kevin de Bruyne.
