England international Rashford tweeted after the game that he was racially abused on his social media accounts.
“He teaches children !! And knows he can freely racially abuse without consequence …”
Manchester United tweeted that they are aware that some of their players have been subjected to racist abuse.

In February, racist symbols were left under an Instagram post by Anthony Martial following United’s 1-1 draw with West Bromwich Albion.
The Premier League, in unison with the rest of English football, organized a social media boycott from April 30 to May 3 to raise awareness of racial abuse directed against players.
In Wednesday’s final, it was Villarreal who took the lead just half an hour away when Gerard Moreno connected on Dani Parejo’s free kick – the first goal scored between these two teams after their previous ones. encounters have produced four goalless draws.
It was Moreno’s 30th goal of the season and Villarreal led at halftime. United managed to equalize in the second half when Edinson Cavani reacted quickly to a blocked shot by Paul Pogba from a corner kick to pass the ball past Gerónimo Rulli.
Despite enjoying more chances throughout the second half, United were unable to take the lead and the game was sanctioned after an uneventful extra time.
The shootout, however, provided some drama.
The teams clashed before De Gea’s penalty was saved by Rulli, giving Villarreal a 1-1 (11-10) victory.
It was the sixth time in the last eight competitions that a Spanish team has won the Europa League, the second tier competition in European football.
