Sergio Aguero does not understand criticism directed at Lionel Messi for Argentina, insisting the superstar is the "first to suffer " and continues to make himself available for the national team.

Messi has won everything on offer during his time as a Barcelona player – the Champions League, LaLiga, UEFA Super Cup, Club World Cup, Copa del Rey and Supercopa de Espana.

However, the six-time Ballon d'Or winner is yet to taste senior success in an Argentina jersey following a runners-up finish at the 2014 World Cup, having also reached back-to-back Copa America finals in 2015 and 2016.

Messi excluded himself from international selection after Argentina's last-16 exit at the 2018 World Cup, before returning and helping the country to the Copa America semi-final last year.

The 32-year-old continues to be criticized for his Argentina performances but countryman Aguero defended his teammate.

"I do not understand those who criticize him in the national team," Aguero told TyC Sports. "He is the first to suffer and continues to come."

The coronavirus pandemic has brought sport to a standstill, with the Premier League and LaLiga among the leagues on hiatus, while the 2020 Copa America has been pushed back to next year.

The Premier League has been suspended since last month and it remains to be seen when, and if, the 2019-20 campaign will resume.

Manchester City star Aguero is contracted until 2021 and the Argentine forward has been linked with a return to boyhood club Independiente.

But Aguero does not know what the future holds, adding: "For now, I'm not thinking about what to do. With all this, the clubs are having problems.

"Up until next year it can be extended for two months or more. There are players who end contracts this year and if it is played in July, August or September, the clubs are going to have problems.

"I don't know if they can renew with players for three months or six. The first thing is to end this season and hit everything next."
