Sergio Aguero is expected to announce his retirement from football aged 33 after the Barcelona striker discovered heart problems on his first start for the club.
The Argentine striker, who moved to the Catalans from Manchester City earlier this year, was diagnosed with cardiac arrhythmia after experiencing chest pains on the pitch.
Aguero, known as one of the best strikers in Premier League history, will undergo a press conference at the Camp Nou on Wednesday morning to discuss his future alongside Barcelona president Joan Laporta, with City boss Pep Guardiola in the crowd.
