Messi doubts Argentina's chances at Copa America

Argentina have reached the past two Copa America finals, but Lionel Messi does not think they are among the candidates to win in Brazil.

Lionel Messi has cast doubt on Argentina's chances of winning this year's Copa America in Brazil.

Messi has twice reached the final of the competition, in 2015 and the Centenario edition in 2016, but on both occasions they were beaten by Chile on penalties.

Argentina have contested four of the past five finals but have lost all of them, with their last continental triumph coming back in 1993 in Ecuador.

And Messi is not convinced they will be challenging in 2019, as he believes the squad is undergoing a transition.

"We go with the same excitement as always, but the reality is that Argentina is going through a process of change," he told TyC Sports .

"It's the first official competition for most of them, but it doesn't mean Argentina are not going looking for the trophy. We're not candidates like other times."

Messi admits his is still feeling the frustration of the end to the club season, with Barcelona having seen their treble dreams dashed in the closing weeks of the campaign.

Although they won LaLiga, a shock 4-0 defeat to Liverpool in the second leg of the Champions League semi-final saw them crash out of Europe, while they were beaten 2-1 by Valencia in the final of the Copa del Rey.

Despite those disappointments, Messi has been feeling good in the Argentina camp ahead of a friendly with Nicaragua on Saturday.

"I'm more tired and frustrated in my head than physically, most of all because of the elimination from the Champions League," he said. "In the last few years, I've played fewer minutes. I feel good.

"I feel very good. It's a really nice group that's very eager to do things well. It's a very good group, with really good people beyond just the footballing sense."
