Fernandez insists last year's controversial video where he taunted France's players during Argentina's World Cup celebrations is now past him and his teammates.
He recalled to GiveMeSport: "What happened (being accused of singing a racist song) is not typical of who I am."
Asked if the episode strengthened his relationship with his team-mates, he replied: "Yes, absolutely."
"It was a tough time, but my team-mates understood me.
"It was a euphoric moment in which I didn't want to hurt anyone. It was just a song that we sing in Argentina as part of 'football folklore', as we call it.
"I tried to apologise to the squad to show my team-mates that I'm not the type to discriminate or judge others. They understood my message and that's where it all ended."
