Casemiro's reaction to Manchester United's elimination from the Europa League has sparked outrage among the club's fans

Casemiro's response to Manchester United's humiliating elimination from the Europa League has provoked the ire of the club's supporters.

After taking a 2-0 lead in the first leg, with Marcel Sabitzer scoring both goals, United encountered a setback when they allowed two peculiar own goals in the closing stages of the match at Old Trafford.

Manchester United's hopes of progressing were dashed when they succumbed to a demoralizing 3-0 defeat to the six-time champions at the Ramon Sanchez Pizjuan in the second leg, despite the Spanish team's current position of 13th in La Liga.

Youssef En-Nesyri struck twice with two absolute gifts from both David de Gea and Harry Maguire, either side of a header from Loic Balde just after half-time.

Sevilla secured their place in the Europa League semi-finals, where they will face Juventus, while Manchester United were eliminated from the tournament. The Red Devils will now have to bounce back and focus on their upcoming FA Cup match against Brighton, which will take place at Wembley on Sunday.

During the Europa League match against Sevilla, Casemiro, who joined Manchester United in a reported £70 million switch, had one of his worst performances in a United shirt. He was booked for the tenth time this season in Andalusia.

Despite his impressive performances this season, Manchester United fans were not happy with Casemiro's post-match behaviour following the defeat to Sevilla in the Europa League.

After the defeat to Sevilla in the Europa League, Casemiro was caught grinning and laughing with referee Arthur Dias on BT Sport cameras. This behavior angered Manchester United supporters who were already frustrated with the team's humiliating loss.

A second tweeted: "Casemiro laughing with the ref right after that dreadful performance?! Clearly not as gutted as the fans standing in the terrace who've paid a fortune to watch that shambles!

A third vented: "Why the f*** is Casemiro smiling I don’t know what there is to smile about."

Another added: "Casemiro laughing with the ref after losing in such a way? Shocking scenes."

A non-United fan weighed in, writing: "Why on earth is Casemiro laughing and joking with the referee after the final whistle when his team have just been humiliated??? That'd infuriate me if I was a Manchester Utd fan."

laughing with the ref right after that dreadful performance?!

A final user commented: "Casemiro laughing with the ref right after that dreadful performance?! Clearly not as gutted as the fans standing in the terrace who've paid a fortune to watch that shambles!"

Erik ten Hag, has criticized the performance and result, labeling them as "unacceptable". He also admitted that such poor displays have occurred "too often" throughout the current season.

Due to a yellow card picked up in the first leg, Manchester United's star player Bruno Fernandes was unavailable for the humbling defeat. However, he will be back and available for the upcoming semi-final clash against Brighton on Sunday.
