Enzo Fernandez has been embroiled in further controversy upon his return to River Plate where fans chanted a discriminatory anti-France song.
The Chelsea midfielder found himself in hot water last week after sharing a video of himself and his Argentina teammates signing the racist chant following the Copa America final triumph.

It led to the Blues' France contingent unfollowing him on Instagram, with Wesley Fofana slamming the 'uninhibited racism' on social media.
Fernandez subsequently apologised over the video, with Chelsea launching an investigation after stating that they condemn 'all forms of discriminatory behaviour'.
And now the 23-year-old has been serenaded by the vile song upon his return to his boyhood club prior to River Plate's 2-2 draw with Lanus.
The ex-Benfica man, who came through River's academy before leaving for Europe in 2022, was treated to a standing ovation.

He came out on the pitch wearing River's home shirt where he proceeded to wave to the thousands of supporters.
In reply, the fans inside the Estadio Monumental chanted the racist song aimed at France's black players in unison to show their support for Fernandez.
The vile and disgusting song, which references the African heritage of a number of the Les Bleus squad, translates to: "They play for France, but their parents are from Angola.
"Their mother is from Cameroon, while their father is from Nigeria. But their passport says French.”

South American football expert Tim Vickery slammed the chant during his appearance on the talkSPORT Breakfast Show on Monday.
He said: "This is a stain glory, they've [Argentina] just won two Copa Americas in a row and the World Cup in the middle of it, and what are we all talking about all over the world?

"How they've poured shame on themselves with this song. Now I don't believe that Argentina is an especially racist country, but there are problems here.
"And these problems come out especially in football. I do Brazilian TV every week, and every week we speak about the same thing, when Brazilian sides meet Argentine sides in the international cup competitions.
"Every week there are monkey gestures and monkey noises coming from the Argentina fans.
"If you talk to the people that do it, they say, 'No, no no, we're not racist, this is just football, this is just part of the game, this is anything that you can do to goad or wind up your opponent is fair game.'"
He added: "What you really want to see from the [Argentina] players is for them to step up and to explain to their own people that, 'This ain't on anymore. We've got to move on, we've got to ditch this.'
"There's so many great things about Argentine football culture, so many of the songs are absolutely fantastic.
"When you go to a game in Argentina, often you come out remembering the songs more than the game, but you don't want to remember this song.
"This is part of history, bin it, and it's up to the players to step up."

It remains to be seen whether Fernandez will face any punishment regarding his involvement in the vile chant being broadcast live.
And while Chelsea teammate Nicolas Jackson has appeared to throw his support behind him, Darren Bent believes his relationship with his French colleagues has been damaged beyond repair.
