Newcastle United condemned on Sunday the discriminatory abuse sent to Bruno Guimaraes and Joe Willock in the wake of a controversy-laden Premier League match against Arsenal that has sparked heavy criticism by the London club about the standard of officiating in England’s top division.

Willock, who is Black, used his Instagram account to highlight racist messages he received after Newcastle’s 1-0 win on Saturday. He is a former Arsenal player and was involved in the build-up to the only goal scored by Anthony Gordon that survived a lengthy video review for three possible infringements.
