Wording in law is
scores in the opponents’ goal:
• directly from their hand/arm, even if accidental, including by the goalkeeper
• immediately after the ball has touched their hand/arm, even if accidental
I’m not convinced by the immediately after part either, given he ran a further 10 yards, took it past/deflected off the ‘keeper and then put it away.
How immediate is immediate?
I don’t agree that the game expected handball, no appeals from Everton defenders or the GK (that I saw) - I’d say the intervention perhaps came as a surprise.
Interesting that there was a similar case with the Antonio goal in West Ham v Fulham game today which where the goal was allowed.
