SPAIN fans booed Barcelona wonderkid Gavi during his victory speech after winning the Nations League.
A tense final saw Spain beat Croatia 5-4 on penalties after the match ended 0-0 at the end of extra-time.
Gavi started the game in a number 10 role but was taken off before extra-time, so did not take a penalty.
After the game Spain's players enjoyed a victory parade and midfielder Fabian Ruiz pushed Gavi forward to speak to the crowd.
The 18-year-old began to address the fans before a small section of them quickly interrupted him by booing and chanting: "Barca b****, Barca b****."
Gavi was taken aback by the reaction, with Spain captain and his Barcelona team-mate Jordi Alba also looking shocked.

Despite the backlash Gavi continued to speak to the fans and thanked them for their support.
He said: "Good afternoon, everyone. I'm going to be brief.
"I wanted to thank all the Spaniards and all the fans who have supported us in these two games, which would not have been possible without them and we will be eternally grateful. Long live Spain."
Gavi is one of the most highly-rated youngsters in the world and that is reflected by his market value of £150million - which places him in the top ten most valuable players.

He already has 21 caps for Spain and his performances for club and country have seen him attract significant transfer interest.
Manchester City, Chelsea and Liverpool have all expressed an interest in signing Gavi, who could be available on a free transfer if Barcelona are unable to register him as a first-team player.
Gavi recently signed a new long-term contract which includes a £870million release clause.
But cash-strapped Barcelona have been unable to register the youngster due to their financial woes.
Despite that Gavi has reiterated his desire to stay at the club, revealing it is his dream to play for Barca.
He said: "I want all of you to be calm on my future… I’m very calm.
"Since I was little I’ve wanted to stay at Barca. It’s my dream club, I always say it.
"Don’t worry, let everyone be calm."
