Manchester United say they are "disgusted" after Axel Tuanzebe and Anthony Martial were racially abused on social media by "mindless idiots" after Wednesday's 2-1 loss to bottom club Sheffield United.

In a statement, the club said: "Everyone at Manchester United is disgusted by the racial abuse received by players via social media after last night's game.

"We utterly condemn it and it is encouraging to see other fans condemn this on social media also.

"Identifying these anonymous mindless idiots remains problematic. We urge social media platforms and regulatory authorities to strengthen measures to prevent this kind of behaviour."
