Sergio Aguero has been told to rest for three months because of a heart problem.
A Barcelona statement said: ‘The player has undergone a diagnostic and therapeutic process by Doctor Josep Brugada and will be out of action during the next three months as the effectiveness of treatment is evaluated.’
The 33-year-old spent Sunday and Monday in hospital in Barcelona as extensive cardiac tests were carried out.

A preliminary diagnosis suggested he was suffering from heart arrhythmia. The former Manchester City striker asked to be taken off after 40 minutes of Barcelona’s draw with Alaves on Saturday night complaining of chest discomfort.
On Monday night, the striker tweeted: ‘I am fine and in good spirits to face the recovery process. I want to thank everyone for so many messages of support and affection that make my heart stronger today.’
Aguero was making his first start at the Nou Camp since his summer transfer.
Speaking ahead of Barca’s Champions League Group E match against Dynamo Kiev in Ukraine on Tuesday, caretaker coach Sergi Barjuan said Aguero remains ‘calm’.

Barjuan said: ‘I talked to him and he’s calm. He’s confined to his room but considering the situation he’s calm.’
Aguero’s former team Manchester City, for whom he scored a record-breaking 260 goals, sent a message of support and wished him well, as did former team-mate Raheem Sterling.
Sterling tweeted on Sunday: ‘Stay strong my brother @aguerosergiokun, we’re all with you. Get well soon.’
