Everton are seeking a formal explanation over why serious claims for a penalty were not fully considered by the match officials in the Merseyside derby against Liverpool at Anfield on Sunday.
Anthony Gordon went down in the Liverpool box under pressure from Joel Matip early in the second half but referee Stuart Attwell dismissed the penalty appeals and the Video Assistant Referee (VAR) did not deem it suitable for intervention and play continued.
The controversial incident has since been heavily scrutinised with Everton manager Frank Lampard's belief his team should have received a penalty backed by a number of pundits and analysts. Even the Professional Game Match Officials Board (PGMOL), the body responsible for match officials in English football, has reportedly said there would have been "no complaints" from them had a penalty been given.
