What happened to Sergio Aguero?

Aguero was handed only his second start for Barca in a Liga clash with Alaves on October 30, but had to be withdrawn early after suffering from chest pains and complaining of dizziness.

The 33-year-old was attended to on the Camp Nou pitch by the club's medical staff before being taken to hospital for cardiological tests and will be kept under observation before undergoing a course of treatment.

How long will Sergio Aguero be out for & which games will he miss?

Barca released a statement confirming that Aguero will be unavailable for selection for the next three months, with a specialised rehabilitation programme set to be undertaken once doctors have decided on the best approach to take with his condition.

"Sergio Aguero has been subjected to a diagnostic and therapeutic process by Dr Josep Brugada," the statement read. "He is unavailable for selection and during the next three months the effectiveness of treatment will be evaluated in order to determine his recovery process."

Aguero is now set to miss around 14 games across all competitions, including La Liga encounters with Celta Vigo, Espanyol, Villarreal, Real Betis, Osasuna, Elche, Mallorca, Granada, Rayo Vallecano and Alaves.

He will also sit out Barca's final two Champions League group-stage outings against Benfica and Bayern Munich, as well as a Supercopa de Espana clash with arch-rivals Real Madrid on January 12.

Will Sergio Aguero have to retire?

It has been suggested that Aguero could be sent into premature retirement from the game after a major health scare, with it reported that he could be suffering from an as of yet undiagnosed heart condition. However, it remains unclear if he will have to retire from playing.

Pep Guardiola, who managed Aguero for five years at Man City, has urged the Argentine to put his long-term health first with regards to any decision on his future in football.

"We wish him well from all the people here at Manchester City, we wish him a safe recovery," Guardiola told a press conference while addressing Aguero's hospital admission. "The time doesn't matter. Health and life are much more important than anything else.

"We wish him as speedy and safe recovery as possible and he comes back, if possible, to play again, otherwise to enjoy his life and what he has done, and to be careful and be safe for the rest of his life."

Has it happened to other footballers?

Aguero is not the only player to see his career put on hold by a chest or heart issue, with the other most recent example coming in the form of Christian Eriksen's sudden collapse at Euro 2020.

The Inter and Denmark midfielder stopped breathing after suffering cardiac arrest and had to be resuscitated on the pitch before being rushed to hospital, where it was eventually confirmed that he would need to be fitted with an implantable cardioverter-defibrillator (ICD).

Former Bolton Wanderers midfielder Fabrice Muamba, meanwhile, was forced to hang up his boots early after a similar incident during an FA Cup clash with Tottenham in 2012, with doctors subsequently revealing that he was lucky to be alive after his heart stopped beating for 78 minutes.

Real Madrid legend and ex-Spain goalkeeper Iker Casillas also retired after suffering a heart attack while in training at Porto in 2019, with the Spaniard announcing his decision a year later at the age of 39.

There is hope that Aguero can return to the pitch, though, with Ajax and Netherlands star Daley Blind still going strong at the age of 31 after being fitted with an ICD two years ago and ex-Stuttgarter Kickers player Daniel Engelbrecht having resumed his career after an on-field heart attack in 2013.
