Former Premier League referee Mark Halsey (pictured) has criticised the appointment of Jon Moss to officiate the FA Cup final. “Seriously, Jon Moss at Wembley? I can’t be having that,” he wrote on social media: “He’s made too many high profile mistakes this season already. Even last weekend he missed two blatant penalties, one for Palace and one for West Brom.” “I reckon we’ll be a laughing stock around the world.”
