Inter Miami captain Lionel Messi reacts as video shows Sergio Aguero appearing to think seriously about shock retirement U-turn for Club World Cup

Aguero released a video on Instagram showing himself sitting in a chair with a pensive look on his face, with the caption, "Thinking about making a comeback for the FIFA Club World Cup", to which Messi replied with the eyes emoji in the comments. However, all is not as it seems, with Aguero's post being sponsored by Michelob beer and presumably not a real hint at a return.

Aguero and Messi played together for Argentina for 15 years, before the former was forced to retire just after he had signed for Barcelona due to a heart condition. They remain close off the field, hence Messi's reply on Instagram.

Aguero's son, Benjamin, is Messi's godson, a demonstration of how close they are. Aguero joined Barcelona in the same summer that Messi left, however, so they never actually played together at club level.

While Aguero may not be serious about featuring at the Club World Cup, Messi most certainly is. His Inter Miami side will feature in the first game of the tournament against Al Ahly on Saturday, June 14.
