The 28-year-old has insisted that, although he appreciates Argentina's national song, he does not need to sing it in order to know what it means for himself and his teammates.

"I get annoyed by the people who attack you without thinking," he told TyC Sports.

"I won't sing the national anthem on purpose. I don't need to sing it to feel it.

"It reaches me, every person feels it in their own way. The Pumas cry, they feel it differently, and that's ok.

"I play with the national team always as a priority and I want to win everything I play."

Messi, who is the Albiceleste's captain, led his country to the FIFA World Cup final in 2014 and the Copa America decider earlier this year, but lost out on both occasions.
