The Brazil international took to social media to make fun of Mikel Arteta’s side using the viral video of the crying-laughing Ghanaian boy.
Arsenal went into the final day of the Premier League season with a slim chance of being crowned champions for the first time in two decades.
The Gunners didn’t have their destiny in their hands and needed Manchester City to drop points for them to usurp Pep Guardiola’s side.
Arteta’s side managed to do their part by recording a 2-1 victory over Everton on Sunday, thanks to goals from Takehiro Tomiyasu and Kai Havertz.
However, Manchester City also got the job done by beating West Ham United 3-1 to restore their two-point lead at the top and be crowned champions for the fourth successive time.
While some rival fans took delight in Arsenal’s failure to win the league, Richarlison joined in the trolls with a rather cheeky social media post.
The Brazil winger shared a video of the viral crying-laughing Ghanaian boy on his Instagram page, accompanied by a laughing emoji.
It will be recalled that eight-year-old Albert Ofosu Nketia went viral in 2023 after a video of him crying and later switching to laughing was shared on social media.
It was later revealed that Albert is autistic, with his mother appealing to the public for their support to cater to his needs.
Meanwhile, Arteta believes Arsenal will come back stronger after losing the Premier League title to Manchester City by just two points.
“They (City) took it away from us. It's the second season. There's only one way to do it - you have to be more determined, you have to be more ambitious, you have to have a lot of courage and push every limit in everything that we have. That's the next step,” he told Sky Sports.
"If we do what we have to do, we're going to be closer and at the end we'll win it. When? I don't know, but if we keep knocking and being that close, in the end it will happen."
Arsenal’s failure to win the Premier League means no Ghanaian player has won the title since Daniel Amartey and Jeffrey Schlupp in 2016 with Leicester City. Thomas Partey came close with the Gunners this season but now has to try again next season.
