The Premier League have reportedly enlisted the help of British Airways pilots to help VAR officials improve their communication to cut out blunders after a number of high-profile incidents this season.
Liverpool's Luis Diaz had a goal wrongly ruled out for offside against Tottenham in September after VAR official Darren England mistakenly thought the goal had been given on the pitch and told the on-field referee to stick with his decision.
Arsenal boss Mikel Arteta then labelled the decision to allow Anthony Gordon's winner for Newcastle against his side earlier this month 'a disgrace' following a lengthy VAR check.
