Let's face it, English referees aren't likely to be going to the World Cup, again.
You can't just make stuff up to 'prove' your point.
Rightly or wrongly Oliver, Taylor and Kavanagh are very highly though of by UEFA - CK was one of the selected non-Elite group referees to attend the UEFA Winter Seminar - so it seems likely that
at least one of them will be at the Euros. Given Kuipers is likely to retire from the FIFA list after the Euros and Rocchi already has that leaves two slots available (assuming UEFA have ten officials at WC22 again). Of those Brych will be 47 by the time the tournament begins, Cakir will turn 46 during it, Lohez will be 45, Mazic will be 45 and Skomina (currently suffering a long term injury) will be 46. It seems incredibly unlikely to me that all eight of those will be at WC22 and so it
seems unlikely that there'd be no English representation - before 2018, the last WC refereeing cohort without English representation was in 1994.
And as for the 'again' part of your post, the lack of English representation at WC18 was nothing to do with anything other that Clattenburg's move abroad. FIFA assemble a large pool (training/seminars/tests etc) of potential WC referees 3 years before the tournament and whittle it down - no one is added, simply removed. Clattenburg was in that pool and nailed on to go given his major appointments under UEFA in 2016. Martin Atkinson was also in the pool but deemed not good enough - remember that 2/3 of the officials selected three years out miss the cut. When Clattenburg decided to leave the UK and thus the pool in early 2017, there was never going to be an English official added in and so there wouldn't be one at the tournament.
Regardless of all of our opinions of PGMOL/PL and Mike Dean yesterday, Oliver and (in particular) Taylor are extremely highly thought of by UEFA and
I'd put money on at least one of them attending the 2022 World Cup. Incidentally, I believe Stuart Attwell is also highly likely to attend both Euro21 and WC22 as a VAR - he's well thought of in that role.
