Claims that Lionel Messi exerts an influence on Argentina's squad selection have been dismissed by the star attacker as a "total lie". 

Messi's brilliant hat-trick in Argentina's FIFA World Cup qualifier against Ecuador last month ensured his side will be at the finals in Russia next year, despite an indifferent qualifying campaign.

Despite his importance on the pitch, the Barcelona forward has been subject to speculation suggesting he holds too much influence over who plays for Argentina.

Inter Milan captain Mauro Icardi, who is married to the ex-wife of Messi's friend Maxi Lopez, had not been selected since 2013 before returning to the group under Jorge Sampaoli.

But Messi is adamant he has never held any sway over the coach's decisions. 

"It was said that I didn't want Icardi coming to the national team, but I've never decided if a player comes or not," Messi said in an interview with TyC Sports in Argentina.

"Now it's coming out that all that was said was a lie. I never said I didn't want Icardi in the national team, nor did I make anyone leave other players out.

"Telling great players that they're only playing because they're Messi's friend is disrespectful and it's also a total lie because I don't run the national team."

While Icardi has been called up by Sampaoli, Juventus striker Gonzalo Higuain has been omitted from recent squads, despite his prolific form in Serie A.

Messi defended Higuain against criticism that he has failed to perform for Argentina in key matches, such as its 2014 FIFA World Cup final loss to Germany and back-to-back Copa America showpiece defeats to Chile in 2015 and 2016, both of which were settled on penalties after goalless draws.

"The truth is that it hurts, everything that was said at this time," Messi said. "We played the final of a World Cup, two Copa America finals, at least two of the three [we] deserved to win.

"We did not win and we all went through that. [Higuain] had the situations he had and they took it against him, but we are used to being told atrocities about us.

"We all had hard times, beyond what was achieved, there was a lot of hard blows to this group. I talk to everyone, we have a great relationship, we have played together for many years and we know each other."

Messi also denied having a problem with Higuain's Juve team-mate Paulo Dybala, who has said he finds it hard to play with the 30-year-old as they occupy similar positions on the pitch.

"There's nothing to clarify with Dybala," Messi said. "I knew what he meant from the first moment."
