Neville constantly looks for a headline to make us look bad. The Arsenal and United games he has come out with "Klopp has lost it, he's gone" when Klopp was having one of his rants on the sideline, then every little thing on the pitch he picks up as some kind of major incident. He knows perfectly well he can control a narrative and people will talk about it more if he pushes it a little bit.
Had he pointed out that Jota was caught by the goalkeeper, and that's enough to take someone off stride and therefore a foul, when running at such a speed (as he well knows, being an ex footballer) then everyone else would have gone along with it, but he used the word dive about 6 times in 2 sentences before the replay was even shown.
It must have been a tough Christmas for him though, having his sister, aunty and wife all round his house and still only making a turkey dinner for 2.
