Frank Lampard did not celebrate Conor Coady's Merseyside derby goal before it was disallowed because he expected it to be ruled out.
Asked why, he initially said: "We're Everton aren't we." The decision to strike it out for offside has since fallen under scrutiny - just like with the Virgil van Dijk tackle on Amadou Onana that drew a yellow, not red card. While far from the most controversial refereeing decisions of the weekend, both appear to occupy frustrating grey areas that have left experienced referees struggling to explain the calls.
The decisions were overshadowed by the fallout from other games - with VAR interventions dismissing goals for Newcastle United and West Ham United that refereeing representative body the PGMOL has reportedly accepted were mistakenly ruled out. Newcastle have submitted an official complaint and a number of Premier League clubs are said to be compiling lists of decisions that have gone against them.
