Barcelona striker Sergio Agüero has announced his retirement from football at the age of 33 - after being diagnosed with a cardiac arrhythmia.
The last time Agüero played was during a match in the Camp Nou against Alaves at the end of October. During his last match, he was taken off during the first half and substituted due to chest pain.
It was later revealed by his team that his high level of discomfort was caused by an arrhythmia and that he would have to undergo treatment for an over three-month period.
Now, after months of regular cardiac exams, professionals have advised him to stop playing football altogether as it would pose a threat to his heart condition and livelilhood—resulting in a very emotional retirement announcement from Agüero.
During a news conference on Wednesday, he said: "This conference is to announce I have decided to stop playing professional football. It is a very difficult moment. The decision I have taken for my health; the problem I had a month and a half ago.”
He continued, “I have been in good hands with the medical staff. I made the decision 10 days ago after doing everything possible to have some hope of playing on. I am very proud for my career. I always dreamed of a professional career since the first time I touched a ball at 5.”
Known as "Kun" amongst his fellow teammates and football fans—comes from the cartoon Kum-Kum—Agüero was a talented player whose professional career to an unfortunate sudden end.
In honor of Agüero’s legacy, many have posted tributes for the football player. We’ve rounded up 19 of the best ones as a nod to his player number at Barcelona.

Occasionally an opposition player comes a long who just breathes football, plays the game, doesn't court controversy, doesn't cheat, doesn't give it the attitude to your fans and you just hugely respect them. These players are surprisingly rare. That's why I loved Sergio Aguero. pic.twitter.com/VqN5QrYTkg

Aguero's last goal with Argentina was from Messi’s assist, and the last assist he made was for Messi.
