What was the origin of Sergio Agüero's injury and what consequences could it bring?

Kun Sergio Agüero was a starter at Barcelona who received Alavés at the Camp Nou for the 12th date of La Liga in Spain. It was the first game of the culé team after the dismissal of Ronald Koeman and it had the presence of the interim Sergi Barjuan in the substitute bench, waiting for the hiring of a new coach, who would be Xavi Hernández.

From the beginning, the Argentine striker showed his personality and hierarchy in the Barcelona attack, determined to change the course of a club that is going through a deep sporting and economic crisis and that seems unable to overcome the departure of Lionel Messi.

However, at minute 38 of the first half, Kun appeared lying on the grass, where he remained for a long time receiving the attention of the doctors, in an image that worried everyone. The television broadcast tried to find the moment when the Argentine striker suffered the injury but it was not seen what was the reason for his ailment.

A few seconds before, Agüero jumped to look for a header in the rival area and in the fall he hit his back against the body of a rival defender. Then, in another replay, he was seen clutching his chest as if something was bothering him to breathe.

Finally, the former Independiente got up and walked out on his own, although he looked quite sore and somewhat dizzy. The degree of injury suffered by Agüero is not yet known.
