Barcelona striker, Sergio Aguero, will be out of action for three months after a cardiac examination.

The LaLiga club confirmed this in a statement on Monday.

The 33-year-old was taken to hospital for tests on his heart, after he was substituted with chest pains in the first-half of Barca’s 1-1 draw with Alaves on Saturday.

The club has now said: “Following a cardiac exam, Barca striker Aguero has undergone a diagnostic and therapeutic procedure with Dr. Josep Brugada today.

“Over the next three months the effectiveness of the treatment will be evaluated to determine when he can come back.”

Aguero has made five appearances for Barca since joining on a free transfer from Manchester City this summer, his only goal for the side coming in the final moments during their 2-1 defeat against Real Madrid in El Clasico.

The situation with Aguero compounds issue at Barca, who are being overseen by interim coach Sergi Barjuan following last week’s sacking of Ronald Koeman. Sources have told ESPN that Barca are in talks to appoint club legend and now-Al Sadd coach Xavi Hernandez.

“Aguero is an important player for us and his absence is a setback,” Barjuan said in a news conference on Monday.

“I spoke to him, exchanged WhatsApps and he is calm. He is in his [hospital] room, locked there as he says but he is calm.”
