LONDON: Crystal Palace winger Wilfried Zaha has accused Manchester United and Liverpool fans of calling him a 'black monkey' on social media. 'If Man United and Liverpool fans feel better by calling me a black monkey in my messages .. feel free to carry on if it makes your day better,' the former Manchester United player posted on Instagram after his team's 2-0 win over West Brom in the Premier League Asia Trophy in Hong Kong on Saturday. Palace manager Frank de Boer had earlier said the 24-year-old Ivory Coast international needed greater protection from referees after he received rough treatment during Saturday's match.
