And my opinion, for what it's worth, is that both Taylor and Oliver will go to the Euros.
Wasn't there a situation with FIFA for the last WC when it was alleged FIFA (Collina?) wanted Clattenburg and the FA put Atkinson's name forward. In the end, both went.
It does seem that UEFA favour Taylor based on recent appointments, but that Oliver has had some backing from FIFA with for example appointments in the U17 and U20 tournaments - including a Final and Semi-Final I recall. Was it Oliver that went to some initial Course for the WC 2022 in Qatar?
