Although Arsenal had been linked with Moises Caicedo, the Ecuadorian midfielder, it was Chelsea that ultimately secured his transfer.
Caicedo's first appearance for Chelsea took place on Sunday, when they faced off against rivals West Ham.
In the aftermath of Moises Caicedo's difficult debut for Chelsea on August 20, some fans are convinced that Arsenal playfully poked fun at their rivals.
Caicedo, who recently joined Chelsea for a British record fee of £115 million during the summer transfer window, made his debut wearing the blue shirt against West Ham United at London Stadium.
Before his move to Stamford Bridge, there were rumors linking the Ecuadorian midfielder to other Premier League clubs, including Liverpool and Arsenal.
Football London reported at that time that the former Brighton midfielder had attracted interest from Arsenal, and the club even submitted bids of £60 million and £70 million for him during the January transfer window.
Ultimately, Chelsea emerged victorious in the competition to secure the 21-year-old player's services from Brighton this summer, with Mauricio Pochettino providing him with his debut opportunity on Sunday.
However, his start with Chelsea was challenging, as he conceded a penalty shortly after coming on as a substitute for Ben Chiwell.
Arsenal's Playful Gesture
Following Moises Caicedo's challenging debut, Arsenal seemingly engaged in a light-hearted taunt directed at Chelsea via Twitter. They posted a well-timed picture of Declan Rice, the former West Ham captain, wearing Arsenal's training kit and accompanied it with a waving hand emoji in the caption.
Fans quickly noticed this gesture and speculated that it could be a playful dig at Chelsea, especially given the ongoing debate about which club boasts the best central midfielder in the league.
One Twitter user, @ArsenalAnoop, pointed out, "We know what you did there," while another, @Ravrmagoat, suggested, "Caicedo owns him."
